Method of facilitating removal of bioorganic stains from surfaces
Protein-polymer composite materials are provided according to embodiments of the present invention that include an admixture of a polymer resin, a surfactant and a non-aqueous organic solvent. An aqueous solution containing bioactive proteins 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 that is useful for facilitating removal of bioorganic stains.
1. A protein-polymer composite material, comprising:
one or more amylases dispersed in a two component non-aqueous organic solvent-borne polymer resin, said amylase in the form of a particle with an average particle size, wherein said average particle size in the protein-polymer composite material is in the range of 10 μm (average diameter) or less.
2. The material of claim 1 , wherein said resin comprises a hydroxyl-functionalized acrylate resin.
3. The material of claim 1 wherein said resin comprises a polyisocyanate crosslinker.
4. The material of claim 1 wherein said amylase is an α-amylase.
5. The material of claim 1 further comprising one or more additives.
