CHEMICAL VAPOR DEPOSITION OF HYDROGEL FILMS

摘要

In one embodiment of the invention, iCVD is used to form non-crosslinked thin films using a radical initiator and an alkene. In another embodiment, iCVD is used to form crosslinked thin films by the addition of a crosslinking agent (e.g., a diacrylate or a dimethyacrylate). In one embodiment, when the crosslinker is EDGA and the monomer is HEMA it results in crosslinked P(HEMA-co-EGDA) copolymer, m another embodiment, when the crosslinker is EDGA and the monomer is VP, it results in crosslinked P(VP-co- EGDA). Disclosed are the effects of crosslinker incorporation on the thermal and the wetting properties of the polymers. The unique swelling properties of these films are also described; certain films of the present invention are hydro gels when soaked in water.
