Abstract

Processes for preparation of a protein-polymer composite material are provided according to embodiments of the present invention which include providing an admixture of a polymer resin, a surfactant and a non-aqueous organic solvent. An aqueous solution containing bioactive proteins and substantially free of surfactant is mixed with the admixture. The emulsion is mixed with a crosslinker to produce a curable composition. The curable composition is cured, thereby producing the protein-polymer composite material.
