Technical Field

The disclosure relates to the field of high polymer materials, in particular to a biomimetic editing method and a biomimetic editing method for a semi-crystalline high polymer material high polymer chain.

Background

A semi-crystalline polymer material is characterized in that polymer chains in the material have both amorphous regions which are randomly arranged and aggregated and crystalline regions which are orderly arranged and aggregated. That is, different polymer chain aggregation states exist at the same time, and even if the polymer chains or segments are amorphous regions or crystalline regions, the arrangement and orientation may be different. I.e. there is a large difference in the aggregate state of the polymer chains or segments in different regions. For example polyetheretherketone, polypropylene.

The polymer chains in different aggregation states enable the semi-crystalline polymer material to present different mechanical states on the macroscopic mechanics of a workpiece, generally, the more orderly the polymer chains are arranged, the stronger the stress strain resistance of the material is, and the material presents high strength and high modulus. Conversely, a material having a polymer chain with disorder in arrangement will exhibit more excellent elongation properties. Therefore, the semi-crystalline polymer material can embody high strength and high rigidity of a high crystalline state and high toughness and high plasticity of a low crystalline state, so that the semi-crystalline polymer material can be widely applied to the fields of aerospace, national defense and military, advanced manufacturing, biological medicine and the like.

Example 1

The embodiment provided by the disclosure, namely the embodiment of the bionic editing method of the semi-crystalline high molecular chain of the high molecular material.

The embodiments of the present disclosure are described in detail below with reference to fig. 1.

Step S101, providing a semi-crystalline polymer material for editing a local part of a bionic body based on the characteristics of the local part, and melting the semi-crystalline polymer material into a first state solution.

The bionic body is a part for simulating the functions of a biological system, breaks the boundary between a biological system and a machine, and communicates various systems, for example, a bionic rib is used for simulating a rib in a human body and can replace a damaged rib of a patient, so that the aim of protecting the thoracic cavity of the human body is fulfilled; because the real ribs of the human body comprise hard bones and cartilage which bear different functions in the human body and show different characteristics, in order to enable the bionic ribs to be closer to the real ribs, the bionic ribs also need to imitate the characteristics of the hard bones and the cartilage; thus, a part of the edited bionic body exhibits the characteristics of hard bone, and another part exhibits the characteristics of cartilage.

The semi-crystalline polymer material refers to a material in which polymer chains have both amorphous regions in disordered arrangement and aggregation and crystalline regions in ordered arrangement and aggregation. That is, different polymer chain aggregation states exist at the same time, and even if the polymer chains or segments are amorphous regions or crystalline regions, the arrangement and orientation may be different. I.e. there is a large difference in the aggregate state of the polymer chains or segments in different regions. For example polyetheretherketone, polypropylene.

Semi-crystalline polymeric materials for providing topical components for editing biomimetics include: powder, wire, and pellet, to which embodiments of the present disclosure are not limited.

A molten substance or material in a molten state is called a melt. When the semi-crystalline polymer material is heated to the temperature higher than the melting point of the semi-crystalline polymer material, the semi-crystalline polymer material will present a first state solution. The melting point temperatures of different semi-crystalline polymeric materials are different. The melt of the semi-crystalline polymer material is a non-newtonian fluid of the polymer material.

The first-state solution may be a semi-crystalline polymer solution formed by polymer chains of any degree of orientation, for example, the first-state solution is a semi-crystalline polymer solution in which polymer chains are oriented at a low degree; or, a semi-crystalline polymer solution with moderately oriented polymer chains; or, a semi-crystalline polymer solution with highly oriented polymer chains; the disclosed embodiments are not to be considered limiting. That is, only the semi-crystalline polymer material is subjected to the heat treatment to be melted into the first state solution, and the semi-crystalline polymer material is not subjected to other treatment.

In some embodiments, the melting the semi-crystalline polymer material into a first state solution comprises the following steps:

step S101a, melting the semi-crystalline polymer material into a first state solution in a 3D print head.

3D printing (i.e., 3 DP), which is a rapid prototyping technology, is also called additive manufacturing, and is a technology that constructs an object by using an adhesive material such as powdered metal or plastic based on a digital model file and by printing layer by layer. The common printer can print planar articles designed by a computer, the 3D printer has the same basic working principle as the common printer, only the printing materials are different, the printing materials of the common printer are ink and paper, and different printing raw materials such as metal, ceramic, plastic, sand and the like are arranged in the 3D printer. The computer controls the 3D printer to superpose the printing materials layer by layer in a dot-line-plane-body high-resolution additive forming mode, and finally, the digital model in the computer is converted into a real object (such as an artificial body). Therefore, 3D printing is also referred to as 3D stereoscopic printing. The 3D printing can be carried out by parts according to the characteristics of the local parts of the real object, and the integrally formed real object is finally generated.

This embodiment melts semi-crystalline polymer material in the form of first state solution in 3D beats printer head through the 3D printer. The 3D printing head is provided with a slender output pipeline for outputting printing raw materials during printing. For the disclosed embodiments, the printing stock material is a melt of the semi-crystalline polymeric material.

And S102, in the process of extruding the slender output pipeline, enabling the first state solution to generate orientation change, and generating a second state solution required by local part bionic.

The molecular chain, chain segment or crystal structure of the crystalline polymer is arranged along the direction of the external force or the flowing direction under the action of the external force, which is called orientation. Ordered orientation is referred to as ideal orientation of the macromolecule. The oriented state is ordered to some extent in one or two dimensions, while the crystalline state is ordered three-dimensionally. For example, in ideal orientation, fiber drawing is uniaxial, and is achieved by applying stress in one dimension of the material by uniaxial stretching; the film articles are biaxially oriented by biaxial stretching, blow molding, and the like.

The second state solution is a semi-crystalline polymer solution with highly oriented polymer chains. For example, the polymer chains in the second state solution have an orientation change of 60% to 100%.

Since the melt of the polymer material is a fluid of the non-newtonian polymer material, the flow of the melt in the elongated pipe causes the polymer chains to flow in an oriented manner. Thus, in some embodiments, an elongated output channel of a 3D print head of a 3D printer is employed, the elongated output channel having preset elongated channel characteristic values required for editing the local part bionics. The preset slender pipeline characteristic value comprises a preset pipeline diameter value and a preset pipeline length value. Further, the diameter value of the preset pipeline is 0.1-50 mm; the preset length value of the pipeline is 0.5 mm-100 mm.

In the slender output pipeline, the orientation degree of the polymer chains is influenced by various aspects such as melt viscosity, melt temperature, melt flow speed and the like. Therefore, the value of the process parameter of the first state solution processed in the elongated output pipeline meets the preset process condition. The process parameter values include a melt temperature value and a melt flow rate value. The temperature value of the solution meets the requirement that the temperature value of the solution is larger than the melting point temperature value of the semi-crystalline polymer material and is smaller than 600 ℃; the melt flow rate value meets 1 mm/s-200 mm/s. According to the embodiment of the disclosure, for different first-state solutions of semi-crystalline polymer materials, by using elongated output pipelines with different pipeline diameters and different pipeline lengths, and by controlling the flow rate and the melt temperature of the first-state solution in the output pipelines, the first-state solution is melted and extruded, so that a semi-crystalline polymer melt (i.e., a second-state solution) with highly oriented polymer chains is obtained.

Step S103, controlling the orientation direction and aggregation state of macromolecular chains in the extruded second-state solution through the relative movement direction generated at the pipeline opening of the elongated output pipeline, and generating an aggregation assembly.

The aggregated morphology, comprising: fibrous aggregated morphology, sheet-like aggregated morphology, and/or globular aggregated morphology.

Wherein, the aggregation assembly of the polymer chains is oriented along the polymer chains, and has great difference with the mechanical property oriented perpendicular to the polymer chains. When editing, the anisotropy of the polymer chains in the aggregate composition can be realized by controlling the relative movement direction. For example, when the edited local part is a soft body, the aggregate assembly of polymer chains can be oriented perpendicular to the polymer chains; when the edited local part is a hard body, the aggregate assembly of polymer chains can be oriented along the polymer chains.

The relative movement direction is the movement direction generated by the pipeline port by taking the substrate which receives the second state solution as a reference object. When the base plate is not moved, the moving direction of the pipeline port is also the relative moving direction; when the base plate moves and the pipeline port does not move, the opposite direction of the moving direction of the base plate is the relative moving direction.

Since the polymer chains in the second-state solution are in a high orientation state, the orientation direction and aggregation state of the polymer chains in the extruded second-state solution can be controlled by the relative movement direction of the opening of the elongated delivery pipe. For example, when the 3D printing is used for biomimetic editing, the motion mechanism is used to control the relative motion between the conduit port of the elongated output conduit of the 3D printing head and the substrate carrying the local component, in the motion process, the conduit port extrudes the second state solution based on the control instruction, and the extruded second state solution depends on the substrate to generate the aggregation assembly.

In some embodiments, the relative motion direction occurring through the duct opening of the elongated output duct controls the orientation direction and aggregation morphology of polymer chains in the extruded second-state solution, comprising the steps of:

step S103a, enabling the pipeline port to move relatively based on the path direction of the preset editing path of the local part, controlling the orientation direction and the aggregation form of polymer chains in the extruded second-state solution, and generating an aggregation assembly.

During bionic editing, if the relative motion direction of the pipeline port of the elongated output pipeline is changed, the orientation direction is changed accordingly. If the relative movement of the pipe orifices is controlled in accordance with the path direction of the preset editing path when editing the partial components, an aggregate assembly of the partial components can be generated. For example, the movement path of the pipeline opening of the 3D printing head is controlled based on the path direction of the preset editing path, that is, the orientation direction and the aggregation change of the polymer chain can be controlled, and a form required for local component bionics such as the same direction, different direction intersections, or concentric circles can be formed. Namely, polymer chain aggregation assemblies with different orientation forms can be obtained by adopting different printing paths.

And step S104, controlling the cooling speed of the aggregation assembly to generate a local part meeting preset crystallization conditions.

Because the macromolecular chains in the second state solution are heated and are in a high-energy-level active state, after the second state solution is extruded and cooled, the macromolecular chains tend to form a low-energy-level metastable state or stable state from the high-energy-level active state. The polymer chains of the polymer are aggregated (crystallized) from disordered arrangement to ordered arrangement. Finally, the aggregation assembly generates local parts required by bionics.

In some embodiments, the controlling the cooling rate of the assembled body to generate the local part satisfying the preset crystallization condition comprises the following steps:

and step S104a, cooling the aggregation assembly based on a preset cooling speed and a preset cooling time to generate a local part with a preset crystallinity and a preset crystal form.

The temperature of the activity and the length of cooling during crystallization determine the degree of ordered aggregation of the polymer chain arrangement. In the present embodiment, during editing, the aggregation assembly is processed and controlled at a preset cooling speed and a preset cooling time, and a local component satisfying a preset crystallization condition is generated. For example, the preset cooling rate is 10 ℃/min to 1000 ℃/min; the preset cooling time is 0.001 s-10 s. The local parts formed by the polymer materials with different degrees of crystallinity, that is, the local parts have different crystal regions, and different polymer chain aggregation forms, for example, a fiber aggregation form, a sheet aggregation form, and a spherical aggregation form, can be obtained by the above control. I.e. the resulting local part has a predetermined crystallinity and a predetermined crystalline morphology.

The different aggregation states of the polymer chains of the semi-crystalline polymer material can bring about great differences in the mechanical properties of the local parts. The strength and modulus of a local part edited by using a polymer material having a polymer chain in a highly amorphous arrangement in the orientation direction are only about half of those of a polymer material in a highly ordered arrangement and aggregation in the orientation direction, but the elongation at break is more than ten times of that of the local part. In addition, the difference between the performance of the polymer chain in the orientation direction and the performance of the polymer chain in the non-orientation direction is 1 to 10 times. Further, even if the degree of order alignment is the same and the mechanical properties in the same orientation direction are the same, there are differences in properties due to differences in the aggregation form of the polymer chains (for example, fibrous aggregation form, flake aggregation form, or spherical aggregation form).

According to the embodiment of the disclosure, the local part of the bionic body can be processed by utilizing the characteristics of the semi-crystalline polymer material, so that the mechanical functionality of the local part is enhanced, and the local part has the function required by the local part of the bionic body.

As shown in fig. 2, the present disclosure provides a biomimetic editing method for a semi-crystalline polymer chain, comprising:

step S201, the biomimetic body is divided into a plurality of local parts based on local characteristics of the biomimetic body.

In step S202, each local part of the bionic body is edited based on the method described in embodiment 1, and an integrally formed bionic body is generated.

The different aggregation states of the polymer chains of the semi-crystalline polymer material can bring great difference to the mechanical properties of the integrally formed bionic body. According to the embodiment of the disclosure, each local part of the bionic body can be accurately edited by using the method described in embodiment 1, and each local part can show different mechanical properties by using the mechanical property difference exhibited by the polymer chains in different aggregation forms, so that the situation that the bionic body adopts a single crystalline state is broken. Different local parts are accurately edited by adopting different control methods and processes through a point-line-plane-body high-resolution processing mode, so that the parts of a high molecular chain are edited, and further, the integrated forming is realized, and the required bionic body is obtained. For example, as shown in fig. 2, the biomimetic body comprises: a first partial component, a second partial component and a third partial component; extruding the second state solution through a long and thin output pipeline, accurately editing a first local part, a second local part and a third local part in sequence, orderly arranging the macromolecular chains of the local parts in respective ordered areas, and generating the local parts with different mechanical properties into an integrally formed bionic body; as shown in fig. 3, "=" denotes a first aggregation morphology (ordered), "+" denotes a second aggregation morphology, "&" denotes a third aggregation morphology (disordered); FIG. 3 shows a schematic representation of the coexistence of highly ordered, moderately ordered, less ordered, and differently oriented regions in various aggregate morphologies within the same biomimetic; as shown in fig. 4, the brick mud structure of the pearl oyster at the lower left, the haves tube structure of the cortical bone, and the columnar interstitial structure of the teeth at the upper left; these are typical structures of typical composites of different modulus materials; after the bionic editing is carried out by using the method of the embodiment of the disclosure, the aggregation form with ordered arrangement in the hexagonal region (ordered region) shown in the right picture is generated, and the aggregation form with disordered arrangement outside the hexagonal region is generated; on the premise of ensuring the strength, the fracture toughness or impact toughness of the material is greatly improved; taking a polyetheretherketone polymer material which belongs to a semi-crystalline polymer material as an example, the tensile strength of the original material is 100MPa, the Young modulus is 4GPa, and the impact strength of a cantilever notch is 25KJ/m2; according to the brick mud structure of pearl oyster, the bionic structure of a polymer chain is edited, the tensile strength can be kept above 90MPa, the Young modulus can be kept above 3.5GPa, and meanwhile, the impact strength of a cantilever beam notch can reach 60KJ/m < 2 >, namely when the toughness and fatigue performance such as impact strength are greatly improved, the small loss of strength and modulus is ensured, and the material becomes a tough integrated material.

According to the semi-crystalline polymer material and the preparation method thereof, various local parts of the bionic body can be processed by utilizing the characteristics of the semi-crystalline polymer material, the mechanical functionality of the local parts is enhanced, the bionic body has the bionic functions of toughness, deformation, hardening and the like, the mechanical functionality of the semi-crystalline polymer material is further enhanced, the situation that the bionic body is in a single crystalline state is broken through, and the application range of the semi-crystalline polymer material is expanded.
