    摘要: Acrylic copolymer pressure sensitive adhesive compositions containing surface-modified nanoparticles are described. The surface-modified nanoparticles are based on nanoparticles having a silica surface and a plurality of silane surface-modifying groups covalently bonded to the silica surface. Although some of the silane surface modifying groups may be non-reactive, at least 25 mole percent, and up to 100 mole percent, of the silane surface-modifying groups are reactive silane surface-modifying groups.

    摘要: Compositions such as photoresists and microfabrication processes are provided that can produce high-fidelity microfabricated structures. The provided photoresists can have reduced swelling during the development phase and can give tight tolerances for products, such as microneedles, that can be used, for example, in the medical field. The provided compositions include a photoresist, a photoinitiator system dispersed in the photoresist, and a polymer-tethered nanoparticle dispersed in the photoresist. The photoresist can be a negative photoresist and the photoinitiator system can include a two-photoinitiator system. The polymer-tethered nanoparticle can include an acrylic polymer and, in some embodiments, can include poly(methyl methacrylate). The nanoparticles can include silica.
