Abstract

In the production of a component (7) having first and second parts (1, 2), at least one of which is of polymer(s), by heating the polymer(s) below their glass transition temperature and contacting the two parts with each other, the polymer is kept below the glass transition temperature using a supercritical gas. An independent claim is included for a component (7) produced by the process.

Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem Verfahren zur Herstellung eines Bauelements, nach der Gattung des Hauptanspruchs. Aus der Patentschrift US 2006/0016556 A1 ist ein Verfahren zur Herstellung eines Bauteils bekannt, bei dem ein Gas mit einem geringen Gasdruck verwendet wird. In der Druckschrift wird dabei offenbart, dass durch die Verwendung des Gases die Glasübergangstemperatur eines Polymers oberflächennah herabgesetzt werden kann. Nachteilig bei dem Verfahren ist jedoch, dass dies nur unter bestimmten Bedingungen und zeitlichen Randbedingungen erfolgt.The invention is based on a method for producing a component, according to the preamble of the main claim. From the patent US 2006/0016556 A1 For example, a method of manufacturing a component using a gas having a low gas pressure is known. The document discloses that the glass transition temperature of a polymer can be reduced near the surface by the use of the gas. A disadvantage of the method, however, is that this is done only under certain conditions and time constraints.

Offenbarung der ErfindungDisclosure of the invention

Das Verfahren zur Herstellung eines Bauelements und das Bauelement gemäß der Merkmale der nebengeordneten Ansprüche hat demgegenüber den Vorteil, dass durch die Verwendung eines überkritischen Gases die Glasübergangstemperatur zumindest eines Polymers ganz gezielt in definierten Bereichen und besonders stark bzw. schnell herabgesetzt werden kann. Vorteilhafterweise muss daher zur Herstellung des Bauelements ein verwendetes Polymer nur noch bis unterhalb der Glasübergangstemperatur erwärmt werden. Hierdurch können Hitzeschäden bei den Teilen, die das Bauelement bilden, dadurch vermieden werden, da zum Zusammenfügen zweier Teile des Bauelements nicht das gesamte Bauelement oberhalb der Glasübergangstemperatur erwärmt werden muss. Des weiteren können die besonderen Eigenschaften eines überkritischen Gases und sein Einfluss auf ein Polymer besonders effektiv bei der Herstellung genutzt werden. Beispielsweise weist Kohlendioxid im überkritischen Zustand ein besonders hohes Lösungsvermögen und eine gasähnliche Viskosität auf.The A method of manufacturing a device and the device according to the features the sibling claims has in contrast the advantage that by using a supercritical gas, the glass transition temperature at least one polymer specifically in defined areas and particularly strong or can be reduced quickly. advantageously, Therefore, for the production of the device a used polymer only are heated to below the glass transition temperature. This allows heat damage be avoided by the parts that make up the component there to join two parts of the device not the entire component above the glass transition temperature to be heated got to. Furthermore, you can the special properties of a supercritical gas and its influence be used on a polymer particularly effective in the production. For example, carbon dioxide in the supercritical state has a particular high dissolving power and a gas-like viscosity.

Vorteilhaft wird als Gas Kohlendioxid (CO2) in einem Druckbereich oberhalb von oder gleich etwa 7,38 MPa, besonders bevorzugt oberhalb von oder gleich etwa 10 MPa, ganz besonders bevorzugt oberhalb von oder gleich etwa 15 MPa verwendet. Weiterhin bevorzugt wird CO2 in einem Temperaturbereich von etwa 32 C° oder darüber verwendet. Durch die Verwendung von CO2 in den oben genanten Druckbereichen und in dem oben genannten Temperaturbereich entsteht überkritisches CO2-Gas. Hierdurch kann die oberflächliche Verflüssigung des zu fügenden Polymers besonders schnell und effektiv erfolgen, so dass der Fertigungsprozess schnell erfolgen kann und empfindliche bzw. kleine Strukturen besser geschützt werden. Die Verwendung von CO2 als überkritisches Gas ist besonders vorteilhaft, da CO2 ein farb- und geruchsloses Gas ist und nach der Herstellung des Bauelements keine Rückstände hinterlässt. Des weiteren ist CO2 im wesentlichen nicht gesundheitsgefährdend, sehr kostengünstig und umweltverträglich.Advantageously, the gas used is carbon dioxide (CO 2 ) in a pressure range above or equal to about 7.38 MPa, more preferably above or equal to about 10 MPa, most preferably above or equal to about 15 MPa. Further preferably, CO 2 is used in a temperature range of about 32 C ° or above. The use of CO 2 in the abovementioned pressure ranges and in the abovementioned temperature range results in supercritical CO 2 gas. As a result, the superficial liquefaction of the polymer to be joined can take place particularly quickly and effectively, so that the production process can be carried out quickly and sensitive or small structures are better protected. The use of CO 2 as a supercritical gas is particularly advantageous because CO 2 is a colorless and odorless gas and leaves no residue after the manufacture of the device. Furthermore, CO 2 is essentially not hazardous to health, very inexpensive and environmentally friendly.

Bevorzugt ist, dass das überkritische Gas nur in oberflächennahe Schichten mindestens eines Polymers bei der Herstellung eindringt. Es ist hierdurch vorteilhaft möglich, die Effekte, die das überkritische Gas auf ein Polymer ausübt, nur in oberflächennahen Schichten zu erzielen. Des weiteren wird bei der Herstellung des Bauelements nur relativ wenig Gas benötigt, da nur soviel Gas bei der Herstellung zur Verfügung gestellt werden muss, wie in die oberflächennahen Schichten des Polymers eindringt. Der Fachmann versteht, dass die Glasübergangstemperatur des Polymers nur in den Schichten gesenkt wird, in denen das überkritische Gas eingedrungen ist.Prefers is that the supercritical Gas only near the surface Layers penetrates at least one polymer in the production. It is thereby advantageously possible the effects that the supercritical Gas on a polymer, only near the surface To achieve layers. Furthermore, in the production of the Component only relatively little gas needed because only so much gas at the production available must be placed as in the near-surface layers of the polymer penetrates. The skilled person understands that the glass transition temperature of the polymer only in the layers is lowered, in which the supercritical gas penetrated is.

Weiterhin ist bevorzugt, dass sich mindestens bei einem Polymer des ersten und/oder des zweiten Teils bereits vor Erreichen der Glasübergangstemperatur des gesamten Bauelements eine fließfähige Schicht an der Oberfläche bildet. Vorteilhaft können die beiden Teile durch die fließfähige Schicht miteinander verbunden werden, wobei die Verbindung dadurch entsteht, dass die beiden Teile mittels der fließfähigen Schicht verklebt bzw. verschweißt werden. Die Verbindung ist dann nach der Abkühlung der fließfähigen Schicht im wesentlichen stabil. Unter Verkleben bzw. Verschweißen soll verstanden werden, dass sich das erste und das zweite Teil mit einander verbinden, beispielsweise miteinander verschmelzen. Der Fachmann versteht, dass eine fließfähige Schicht eines Polymers wie eine Art Klebeschicht wirkt, die beispielsweise mittels Adhäsion eine Verbindung zu einem anderen Gegenstand herstellt.Farther It is preferred that at least one polymer of the first and / or the second part before reaching the glass transition temperature the entire device forms a flowable layer on the surface. Can be advantageous the two parts through the flowable layer interconnected with each other, whereby the connection arises that the two parts are glued by means of the flowable layer or welded become. The compound is then after cooling the flowable layer essentially stable. Under gluing or welding should be understood that the first and the second part with each other connect, for example merge together. The expert understands that a flowable layer a polymer acts like a kind of adhesive layer, for example by adhesion connects to another item.

Bevorzugt weisen das erste und/oder das zweite Teil Kanäle und/oder Aussparungen auf, wobei trotz Erwärmung mindestens eines Polymers des ersten und/oder des zweiten Teils die Kanäle und/oder die Aussparungen im wesentlichen erhalten bleiben. Es ist hierdurch vorteilhaft möglich, ein Bauelement mit Aussparungen und/oder Kanälen sehr einfach durch Erwärmen mindestens eines Polymers herzustellen, wobei jedoch Kanäle und/oder Aussparungen durch das Erwärmen des Polymers nicht zerstört werden. In vorteilhafter Weise wird bei der Verwendung von überkritischem Gas nur die Glasübergangstemperatur von oberflächennahen Schichten gesenkt, so dass bei einer Erwärmung des Polymers nur die oberflächennahen Schichten bereits vor Erreichen der Glasübergangstemperatur fließfähig werden. Ist die Eindringtiefe des überkritischen Gases geringer als die Breite eines Kanals oder einer Aussparung, wird die Struktur des Kanals oder der Aussparung im wesentlichen durch die Erwärmung nicht verändert (keine Gefahr von „Strukturkollaps). Unter einer Aussparung soll verstanden werden, wenn in einem Bereich des ersten und/oder des zweiten Teils Material ausgespart wurde. Unter einem Kanal soll verstanden werden, wenn sowohl das erste Teil wie auch das zweite Teil eine Aussparung aufweist, wobei beim Zusammenfügen der Teile die Aussparung des ersten Teils und die Aussparung des zweiten Teils im wesentlichen übereinanderliegen.Preferably, the first and / or the second part channels and / or recesses, wherein despite heating at least one polymer of the first and / or the second part, the channels and / or the recesses remain substantially preserved. It is thus advantageously possible to produce a device with recesses and / or channels very easily by heating at least one polymer, but channels and / or recesses are not destroyed by the heating of the polymer. Advantageously, when using supercritical gas, only the glass transition temperature of near-surface layers is lowered, so that when the polymer is heated, only the layers near the surface become fluid even before reaching the glass transition temperature. If the penetration depth of the supercritical gas is less than the width of a channel or recess, the structure of the channel or recess will not be substantially altered by the heating (no risk of "structural collapse"). Under a recess should be understood if in a region of the first and / or the second part material was recessed. A channel is to be understood when both the first part and the second part has a recess, wherein when joining the parts, the recess of the first part and the recess of the second part are substantially superimposed.

Besonders bevorzugt umschließt das Bauelement zumindest teilweise ein Element. Beispielsweise kann sich ein Element in einer Aussparung eines der beiden Teile befinden und wird mittels des anderen Teils abgedeckt. Es ist jedoch auch denkbar, dass das Element von dem anderen Teil nur teilweise oder überhaupt nicht abgedeckt wird. In den beiden letzten Fällen ist das Element folglich nicht vollständig von dem Bauelement eingekapselt und hat weiterhin Kontakt zu der Umgebung des Bauelements. In vorteilhafter Weise ist es hierdurch möglich, ein Element durch das Bauelement zu schützen (beispielsweise vor Verschmutzung oder Feuchtigkeit). Wird das Element nur teilweise von dem Bauelement umschlossen, können die umschlossenen Bereiche des Elements von dem Bauelement geschützt werden, wohingegen nicht umschlossene Bereiche des Elements Kontakt zu der Umwelt haben können.Especially preferably encloses the device at least partially an element. For example, can an element is located in a recess of one of the two parts and is covered by the other part. It is, however conceivable that the element of the other part only partially or at all is not covered. In the last two cases, the element is consequently not completely encapsulated by the device and still has contact with the Environment of the device. Advantageously, it is thereby possible, to protect an element by the device (for example from contamination or moisture). If the element is only partially enclosed by the device, can the enclosed areas of the element are protected by the device, whereas unenclosed areas of the element make contact with the Environment.

Insbesondere für Sensoren ist eine nur teilweise Umschließung des Elements von dem Bauelement vorteilhaft.Especially for sensors is an only partial enclosure the element of the device advantageous.

Bevorzugt ist das Element ein Protein, insbesondere ein Enzym und/oder eine oder mehrere lebende Zellen. Der Fachmann versteht, dass das Umschließen eines Enzyms, eines Proteins oder einer lebenden Zelle bei gleichzeitiger Erhaltung der Funktion oder der Lebensfähigkeit des Elements nur bei geringen Temperaturen erfolgen kann. Das erfindungsgemäße Verfahren ermöglicht die Umschließung solcher Elemente, da ein Polymer durch die Verwendung von überkritischem Gas nur noch unterhalb der Glasübergangstemperatur erwärmt werden muss. Die fließfähige Schicht, die zur Verbindung mit dem anderen Teil benötigt wird, entsteht folglich bereits bei niedrigeren Temperaturen als ohne die Verwendung von überkritischem Gas. Da das Element bei der Erwärmung des Polymers zwangsläufig miterwärmt wird, ist die Herabsetzung der Temperatur ein wesentlicher Vorteil.Prefers the element is a protein, in particular an enzyme and / or a protein or several living cells. The skilled person understands that enclosing a Enzyme, a protein or a living cell at the same time Preservation of the function or viability of the element only at low Temperatures can be done. The inventive method allows the enclosure of such elements as a polymer by the use of supercritical Gas only below the glass transition temperature heated must become. The flowable layer, which is needed to connect to the other part, thus arises even at lower temperatures than without the use of supercritical Gas. As the element in the heating of the polymer inevitably miterwärmt is the lowering of the temperature is a significant advantage.

Bevorzugt wird als Polymer Poly-Methyl-Meta-Acrylat und/oder Polystyrol verwendet. Denkbar sind jedoch auch andere Polymere. Des weiteren ist denkbar, dass ein Teil aus mehr als einem Polymer besteht, wobei die verschiedenen Polymere bevorzugt unterschiedliche Glasübergangstemperaturen aufweisen. Hierdurch ist es möglich, dass eines der Polymere bereits bei geringen Temperaturen eine fließfähige Schicht aufweist, wobei die Temperatur, die für eine fließfähige Schicht benötigt wird, durch die Verwendung von überkritischem Gas weiter gesenkt werden kann. Es ist folglich vorteilhaft möglich, das Bauelement bei sehr geringen Temperaturen herzustellen, wodurch auch das Umschließen von sehr temperatursensiblen Elementen, insbesondere Biomoleküle, ermöglicht wird.Prefers is used as a polymer poly-methyl-meta-acrylate and / or polystyrene. However, other polymers are also conceivable. Furthermore, it is conceivable a part consists of more than one polymer, the different ones Polymers preferably have different glass transition temperatures. This makes it possible that one of the polymers already at low temperatures, a flowable layer wherein the temperature needed for a flowable layer is through the use of supercritical Gas can be lowered further. It is thus possible in an advantageous manner Produce device at very low temperatures, which also enclosing of very temperature-sensitive elements, in particular biomolecules, is made possible.

Ein weiterer Gegenstand der vorliegenden Erfindung ist ein Bauelement, das nach dem oben beschriebenen Verfahren hergestellt wird. Das Bauelement weist dabei bevorzugt zwei Teile auf, wobei mindestens eines der Teile ein Polymer umfasst. Denkbar ist jedoch auch, dass beide Teile ein Polymer umfassen oder ein oder mehreren Polymeren umfassen oder das nur ein Teil mehr als ein Polymer umfasst. Es ist weiterhin denkbar, dass eines der Teile oder beide Teile zwei Polymere aufweist bzw. aufweisen, wobei eines der Polymere nur oberflächennah ausgebildet ist und eine vergleichsweise niedrige Glasübergangstemperatur aufweist und das andere Polymer eine hohe Glasübergangstemperatur aufweist. In vorteilhafter Weise ist es so möglich, das Polymer mit niedrigerer Glasübergangstemperatur als eine Art Kleber bei der Herstellung zu verwenden, während das andere Polymer im wesentlichen seinen Zustand trotz der Erwärmung nicht ändert. Es ist weiterhin auch denkbar, dass ein Teil lediglich ein Polymer mit einer vergleichsweise niedrigen Glasübergangstemperatur und ein weiteres, nicht polymeres, Material aufweist. Bevorzugt ist in diesem Fall das Polymer nur an der Oberfläche oder in oberflächennahen Schichten des Teils vorhanden. In beiden Fällen, in denen das Polymer nur an der Oberfläche oder in oberflächennahen Schichten des Teils vorhanden ist, kann das Polymer als Kleber verwendet werden. Es ist durch ein Polymer mit einer vergleichsweise niedrigen Glasübergangstemperatur vorteilhaft möglich, zwischen zwei Teilen einen Kontakt herzustellen.One Another object of the present invention is a component, which is prepared by the method described above. The Component preferably has two parts, wherein at least one of the parts comprises a polymer. However, it is also conceivable that both parts comprise a polymer or comprise one or more polymers or which comprises only a part more than one polymer. It is still conceivable that one of the parts or both parts has two polymers or have, wherein one of the polymers only near the surface is formed and has a comparatively low glass transition temperature and the other polymer has a high glass transition temperature. Advantageously, it is possible to lower the polymer Glass transition temperature to use as a kind of glue in the production while the other polymer essentially does not change its state despite the heating. It is also conceivable that a part of a polymer with a comparatively low glass transition temperature and a further, non-polymeric material. Preferred is in this Case the polymer only at the surface or near the surface Layers of the part available. In both cases where the polymer only on the surface or near the surface Layers of the part is present, the polymer can be used as an adhesive become. It is made by a polymer with a comparatively low Glass transition temperature advantageously possible, make contact between two parts.

Bevorzugt ist das Bauelement ein Mikrofluidik-Bauelemet oder ein Sensor. Bevorzugt wird das Bauelement als Sensor oder als Biosensor verwendet.Prefers the device is a microfluidic device or a sensor. Prefers the device is used as a sensor or as a biosensor.

Ganz besonders bevorzugt ist das erste und/oder das zweite Teil mittels eines Hot-Embossing-Verfahrens strukturiert vorgesehen. Als Strukturierung können beispielsweise Stege und/oder Aussparungen vorgesehen sein. Durch das erfindungsgemäße Verfahren können die so strukturierten Teile dann zu dem Bauelement zusammen verklebt bzw. verschweißt werden. Der Fachmann versteht, dass bei einem Hot-Embossing-Verfahren ein Material als Ganzes sehr stark erhitzt bzw. erwärmt wird, damit dem Material mittels einer Prägeform Strukturen eingeprägt werden können. Der Fachmann versteht weiterhin, dass die erzeugten Strukturen nach der Herstellung zerfliesen würden, wenn das Teil noch einmal stark, das heißt insbesondere über die Glasübergangstemperatur, erwärmt würde. Durch eine Kombination aus dem Hot-Embossing-Verfahren und dem erfindungsgemäßen Verfahren können so die Vorteile des Hot-Embossings-Verfahrens (Erzeugung kleiner Strukturen mittels Prägeform) genutzt werden und gleichzeitig temperatursensible Elemente von dem Bauteil umschlossen werden, ohne dass Aussparungen, Stege oder Kanäle bei der Umschließung zerfließen würden oder die temperatursensiblen Elemente zerstört werden würden.Most preferably, the first and / or the second part is provided structured by means of a hot embossing method. As structuring, webs and / or recesses may be provided, for example. By the method according to the invention, the parts thus structured can then be glued or welded together to form the component. The skilled person understands that in a hot embossing process, a material as a whole is heated or heated very much, so that the material can be embossed by means of a stamping mold structures. The skilled person further understands that the structures produced would be torn off after the production, if the part is still a times strong, that is in particular on the glass transition temperature, would be heated. By a combination of the hot embossing method and the method according to the invention, the advantages of the hot embossing method (production of small structures by means of the embossing mold) can be utilized and at the same time temperature-sensitive elements can be enclosed by the component without recesses, webs or channels would melt in the enclosure or the temperature sensitive elements would be destroyed.

Ausführungsformen der Erfindung sind in den Zeichnungen dargestellt und werden in den nachfolgenden Beschreibungen näher erläutert. Kurze Beschreibung der Zeichnungenembodiments The invention are illustrated in the drawings and in the following descriptions. Short description of drawings

Ausführungsform(en) der ErfindungEmbodiment (s) the invention

In der 1 ist schematisch ein erfindungsgemäßes Bauelement 7 dargestellt. Das Bauelement 7 umfasst ein erstes Teil 1 und ein zweites Teil 2, wobei mindestens das erste Teil 1 oder das zweite Teil 2 ein Polymer umfassen. Das zweite Teil 2 weist Aussparungen 3 auf, wobei in einigen Aussparungen 3 ein Element 4 liegt. Das erste Teil 1 kann so auf das zweite Teil 2 gelegt werden, dass die Elemente 4 durch Zusammenfügen der Teile 1, 2 eingeschlossen oder teilweise eingeschlossen werden. Des weiteren ist in der 1 ein Ausschnitt 8 gekennzeichnet, der in der 2 vergrößert dargestellt wird.In the 1 is schematically a device according to the invention 7 shown. The component 7 includes a first part 1 and a second part 2 , where at least the first part 1 or the second part 2 comprise a polymer. The second part 2 has recesses 3 on, taking in some recesses 3 an element 4 lies. The first part 1 so can on the second part 2 be laid that the elements 4 by assembling the parts 1 . 2 included or partially included. Furthermore, in the 1 a section 8th marked in the 2 is shown enlarged.

Die 2 stellt schematisch das Bauelement 7 mit einer fließfähigen Schicht 5 im Bereich des ersten Teils 1 und des zweiten Teils 2 dar. Die fließfähige Schicht 5 befindet sich nur in oberflächennahen Schichten 9 der Teile 1, 2 und entsteht durch die Herabsetzung der Glasübergangstemperatur in diesen Bereichen 9 und durch das Erwärmen der Teile 1, 2 bis unterhalb der Glasübergangstemperatur des Vollmaterials. Zur Herabsetzung der Glasübergangstemperatur dringt ein überkritisches Gas, insbesondere CO2, in die Bereiche 9 ein. Beim Erwärmen des ganzen Teils 1, 2 beginnen die Bereiche 9 aufgrund der herabgesetzten Glasüberhangstemperatur, noch vor Erreichen der Glasübergangstemperatur des Vollmaterials in einen flüssigen Zustand überzugehen. Ein Steg 6 oder eine andere vergleichsweise kleine Struktur wird dabei zwar auch oberflächennah erwärmt, ändert aber im wesentlichen nicht seine Form durch die Erwärmung. Die Aussparungen 3 und die Stege 6 können so trotz der Erwärmung erhalten bleiben. Zudem müssen die Teile 1, 2 wegen der Herabsetzung der Gasübergangstemperatur nur auf einen geringere Temperatur erwärmt werden bis eine fließfähige Schicht 5 entsteht, wodurch auch temperatursensible Elemente 4 im Bauelement 7 integriert werden können. Wird das erste Teil 1 mit dem zweiten Teil 2 in Kontakt gebracht, so entsteht eine Verbindung zwischen dem ersten Teil 1 und dem zweiten Teil 2, wenn zumindest eines der Teile die fließfähige Schicht 5 aufweist. In diesem Fall verkleben bzw. verschweißen das erste Teil 1 und das zweite Teil 2 miteinander. Durch die Bildung einer fließfähigen Schicht 5 noch vor der Glasübergangstemperatur des Vollmaterials ist die Herstellung des Bauelements 7 besonders schnell, so dass der Fertigungsprozess zeitlich verkürzt wird.The 2 schematically represents the device 7 with a flowable layer 5 in the area of the first part 1 and the second part 2 dar. The flowable layer 5 is located only in near-surface layers 9 Of the parts 1 . 2 and is due to the lowering of the glass transition temperature in these areas 9 and by heating the parts 1 . 2 below the glass transition temperature of the solid material. To reduce the glass transition temperature, a supercritical gas, in particular CO 2 , penetrates into the regions 9 one. When heating the whole part 1 . 2 the areas start 9 due to the reduced glass overhang temperature, before reaching the glass transition temperature of the solid material in a liquid state. A jetty 6 or another relatively small structure is heated while also near the surface, but does not substantially change its shape by the heating. The recesses 3 and the footbridges 6 so can be preserved despite the warming. In addition, the parts must 1 . 2 because of the reduction of the gas transition temperature can only be heated to a lower temperature until a flowable layer 5 arises, whereby also temperature-sensitive elements 4 in the component 7 can be integrated. Will be the first part 1 with the second part 2 brought into contact, it creates a connection between the first part 1 and the second part 2 if at least one of the parts is the flowable layer 5 having. In this case, glue or weld the first part 1 and the second part 2 together. By forming a flowable layer 5 even before the glass transition temperature of the solid material is the production of the device 7 particularly fast, so that the manufacturing process is shortened in time.
