These nanocomposites have wide ranging applications from industrial to medical use.Type: GrantFiled: February 1, 2011Date of Patent: January 8, 2013Assignee: FPInnovationsInventors: Wadood Y.

Patent number: 8299172Abstract: A method for producing biodegradable plastic from natural materials containing polysaccharides by treating the polysaccharide-containing materials with a basic aqueous solution, subsequently treating the mixture with a modifying material that converts pendant hydroxyl groups at any carbon atom of the anhydroglucose units of the saccharide to create polysaccharide carboxylate, and then reacting the product with proteins to produce a biodegradable copolymer with electrostatic chemical bonds between protein and polysaccharide carboxylate molecules. The process provides relatively inexpensive methods for preparing biodegradable plastics that are useful for manufacturing various articles.Type: GrantFiled: January 14, 2008Date of Patent: October 30, 2012Assignee: Saginaw Valley State UniversityInventors: Christopher H. Schilling, David S. Karpovich, Piotr Tomasik
