Definitions
- the invention relates to a molded body with a structured surface for the reversible adhesion of objects or on surfaces and methods for detachment of such structures.
- the molding can be easily detached again from the objects or surfaces.
- the molecular adhesion between two objects can be enhanced or controlled by fiber-like surface structures.
- This principle is known as gecko effect. If a structured elastomer surface is pressed with a certain pressure force against a comparatively flat surface, van der Waals interactions can form.
- the reverible liability ie the possibility of switching attachment and detachment, is also known from nature.
- shear adhesion ie adhesion in the direction of the substrate / obj ektoberflache used who should.
- normal adhesion ie an adhesion force perpendicular to the object surface, the detachment must be initiated differently.
- Adhesive structures and the object surface to vary selectively in order to switch between adhesion (large contact area) and detachment (small contact surface) and thus the selective detachment to he possible.
- E is the modulus of elasticity
- I is the area inertia model
- L is the length (height) of the projection
- n is a factor in front of the mechanical clamping of the projection.
- the object of the invention is to provide a structure which, in particular in the case of normal adhesion, enables a simple selective detachment, and a method for detaching such structures.
- the object is achieved by a shaped body having a structured surface, wherein the surface has a structuring which comprises a multiplicity of projections (pillars) which each have at least one stem and comprise an end face pointing away from the surface. With this end face the projections come into contact with the surface of the adherent object.
- the modulus of elasticity of the projections is constant, but may also have an axial or lateral gradient.
- protrusions with an aspect ratio of less than 10 can be detached particularly easily. So these projections can be deformed by a shearing load parallel to the adhesive surface. The projections are deformed depending on their bending stiffness (E * I). This also reduces the adhesive force and removes the structure. It does not depend on the Scherfes activity of the adhesive bond, but the deformation of the
- Structures leads to a reduction in the adhesion force. Structures which are easily bent can easily be removed by this mechanism.

In one embodiment this aspect ratio up to 5, in particular up to 3. This also applies to the minimum diameter of the projections. This is relevant if the projections have a minimum and a maximum diameter, for example, in the case of an oval base.
