Process for printing an adhesive pattern on a polymer brush extending at the surface of a support (1), forming a nanometric anti-fouling layer (2), the process comprising the following steps:—placing the layer (2) in contact with a first aqueous solution (4) containing a benzophenone,—then illuminating the layer with radiation (3) at a wavelength within the absorption spectrum of benzophenone, according to the pattern and according to a surface energy.

Dry adhesive

A selective adhesive mechanism comprises an engineered surface structure or substrate and a compliant member. The compliant member is able to be a dry and non-tacky substance. The compliant member is selectively adhesive to the engineered surface when the compliant member is in contact with the engineered surface. The compliant member shows adhesion to the engineered surface when the compliant member is within a pre-selected range of hardness. In some embodiments, the compliant member comprises a polymeric member, a thermoplastic elastomer, silicone, polyurethane, or a combination thereof.

DEVICES AND METHODS FOR CONTACTING LIVING TISSUE
20220184268 · 2022-06-16 · ·

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that, when applied to or implanted in living tissue or similar surfaces, displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.
