Abstract
Lactose-derived hydrogels include at least lactose and methacrylic anhydride. A method of preparing lactose-derived hydrogels includes copolymerizing lactose methacrylate, methacrylic acid, and sodium methacrylate using light-induced photopolymerization. Polymerization proceeds in the absence of a photoinitiator. No volatile organic compounds or waste are produced by the method. The lactose may be provided by a milk permeate waste stream from the dairy or food processing industry.
