A moulded body includes a structured surface, wherein the surface has a structuring including a plurality of protrusions (pillars), at least each having a stem and comprising an end face pointing away from the surface. With this end face, the protrusions come into contact with the surface of the adhered object, wherein at least one protrusion comprises at least one structural feature, which, when loading the protrusion, leads to a directed deformation of the protrusion by changing the adhesion.

Moulded body comprising a structured surface for controlled adhesion

A molded body with a structured surface for reversible adhesion to surfaces includes projections having an aspect ratio of up to 10. The structure can be easily detached from the surface by a lateral movement.

Shaped body having a structured surface for reversible adhesion

A structure with improved adhesion includes projections and a backing layer, the rigidity of the backing layer being variable, and the end faces defining a common surface.

Structure with improved adhesion

An object includes at least two faces which are suitable for dry adhesion and differ in their adhesion parameters. By suitable structuring, it is possible, where appropriate in combination with a suitable contact pressure, to selectively control the detachment of surfaces contacted on these faces.

Double-sided reversible adhesive structure

A device having a structured coating for adhering to rough, in particular biological, surfaces, includes a carrier layer, wherein a plurality of protrusions is arranged on the carrier layer, which protrusions each comprise at least a shaft having an end face pointing away from the surface, and wherein a further layer is arranged at least on the end face, wherein the layer has a different modulus of elasticity than the protrusion in question. The further layer can also fill the intermediate spaces between the protrusions such that an internal structured coating is produced.

A method for producing metal structures includes an initiator composition comprising a photocatalytic substance being applied to a substrate. A precursor composition that can be reduced to a metal by the photocatalytic activity of the nanodusts is applied to the layer. A structure template is then applied, partially displacing the precursor composition, and then the substrate is illuminated. Structured metal structures are thus generated.

Composite pillar structures, in particular for adhesion to soft and rough surfaces, include in the longitudinal direction at least one region with lower elasticity modulus and at least one region with higher elasticity modulus. The region with lower elasticity modulus preferably includes an end face, wherein the two regions adjoin one another.

Composite pillar structures

A surface with selectable adhesion is achieved by a shape memory alloy that is at least partly coated with a polymer forming a surface structure, thus allowing the adhesion force of the surface to be controlled.

Object with selectable adhesion

A method for producing finely structured surfaces, in particular in plastics, includes a) applying at least one coating compound on at least one substrate; b) forming a fine structure by a die, which has the negative of a fine structure, c) curing the resultant finely structured coating compound, obtaining a substantially cured coating; and d) separating the finely structured coating from the die, wherein steps d) and c) can also be carried out in the reverse order.

Method for producing finely structured surfaces

A combination includes a first device and a second device, wherein both devices comprise at least one surface and the surface of the first device comprises at least one recess. At least one contact surface is formed when the surface of the first device attaches to the surface of the second device. By applying external pressure, the adhesion force between the two devices can be switched back and forth between at least two states.

Device having controllable adhesion

Described are methods for surface modification of an object () in order to increase the adhesive power of the object, wherein the surface () is subjected to structuring so that a multitude of projections () are formed, each comprising a foot part and a head part, wherein the head part comprises a front surface () which faces away from the surface, wherein each projection () is made in a size such that all front surfaces () project to the same vertical height above the surface (), and form an adherent contact surface () which is interrupted by mutual spacing between the front surfaces ().
