Abstract
A polymer composite comprises a base material, and a polymer membrane provided on at least a part of the base material, the polymer membrane having at least hydrophilicity, and the polymer composite is used in a state exposed to water or a water-based solvent. The polymer membrane is a resin film formed by photo-crosslinking a photosensitive resin composition consisting essentially of a water-soluble polymer, and during crosslinking of the photosensitive resin composition, some of photosensitive groups of the photosensitive resin composition are bound to amino groups fixed to the surface of the base material, whereby the resin film is fixed to the base material.
Claims9
A polymer composite comprising a base material and a polymer membrane provided on at least a part of said base material, said polymer membrane having at least hydrophilicity, said polymer composite being used in a state exposed to water or a water-based solvent.
- wherein said base material per se has amino groups exposed at a surface thereof, and
- said polymer membrane is a resin film formed by photo-crosslinking a photosensitive resin composition consisting essentially of a water-soluble polymer having azido groups as photosensitive groups,
- wherein when the amino groups present on the surface of the base material and photosensitive groups present in said photosensitive resin composition are irradiated with light, some of the amino groups and some of the photosensitive groups undergo a chemical reaction to form a covalent bond, and wherein said resin film is fixed to said base material by said covalent bond.
