Definitions

  • the invention relates to an element with a fine, in particular microscopic surface pattern of hydrophilic stripes and hydrophobic areas lying between the hydrophilic stripes, the distances between adjacent hydrophilic stripes and their stripe widths being coordinated with one another in such a way that the hydrophobic areas between the hydrophilic stripes form drying zones that repel moisture extremely strongly.
  • a further application example is the use of elements according to the invention as capacitor elements that remove moisture from their surroundings.
  • elements according to the invention When cooling to below the dew point, condensation takes place in the area of the hydrophilic stripes, the condensed water being immediately drained along the hydrophilic stripes (“channels”) under the effect of the laplace pressure mentioned above.
  • the elements of the invention can therefore be used effectively as elements for drying their surroundings.
  • optical elements can be realized that do not fog up in the area of the drying zones - even in extremely humid environments.
  • An element according to the invention can in principle be implemented as a layer that adheres to a carrier material.
  • the area should be considered, for example, to coat the lens of a microscope accordingly. Microscopy can then be carried out through the hydrophobic areas (dry zones) even in a very humid environment, the “channels” possibly causing an acceptable loss of light intensity.
  • the preparation of a mirror with a relevant surface pattern according to the invention can also be used.
  • micromechanical valves to control liquid flows on a microscopic scale.

  • Such micromechanical valves have a complicated, complex structure and can only be miniaturized to a very limited extent. Their function is based on the use of closed channels that easily clog, and the easier the smaller the channels or the higher the degree of integration of a component in question.
  • two opposing elements according to the invention are brought together closely with their hydrophilic / hydrophobic structured surfaces and the surfaces are aligned with one another in such a way that with water or hydrophilic strips occupied by aqueous solutions are in alignment with one another, so fluid bridges spontaneously form from one hydrophilic strip to the opposite hydrophilic strip between the two elements, the fluid bridges permitting liquid transport from one element to the other element.
  • the fluid bridges can be destroyed in a targeted and reversible manner if the distance between the two elements is increased and / or the alignment or overlap of the hydrophilic strips, for example by lateral movement of the two elements relative to one another, at least to a certain extent picks up.

  • the hydrophilic strips 4 have a width b of approximately 30 ⁇ m.
  • the distance c between adjacent hydrophilic strips 4 is approximately 60 ⁇ m and thus corresponds to approximately twice the width of the hydrophilic strips 4. If desired, the distances c could also be smaller and correspond, for example, to the width b.

  • the fluid bridge 7 has been broken up again into channels 5, so that there is no longer any material exchange between the two hydrophilic strips 4.

Abstract

L'invention concerne un élément dont la surface présente un motif microscopique composé de bandes hydrophiles (4) et de zones hydrophobes (6) intercalées entre les bandes hydrophiles (4). La distance (c) séparant les bandes hydrophiles (4) juxtaposées et la largeur (b) de ces bandes hydrophiles (4) sont ajustées l'une à l'autre de telle façon que les zones hydrophobes (6) intercalées entre les bandes hydrophiles (4) constituent des zones sèches fortement hydrophobes. Des composants électroniques sensibles à l'humidité, par exemple, peuvent être intégrés dans ces zones sèches. Cet élément peut également être utilisé comme élément condenseur destiné au séchage. Les éléments selon l'invention conviennent également à la réalisation de fonctions microvalve.
