Introduction
In order to reduce the environmental pollution caused by polymer materials wastes, biodegradable polymers, such as starch, chitosan, poly L-lactic acid and poly amino acid, have been paid more and more attention recently [1]. γ-PGA is a hydrophilic, completely biodegradable, and naturally available biopolymer produced by the Bacillaceae family. γ-PGA and its derivatives have been applied in a broad range of fields such as food, superabsorbent polymer, cosmetics, medicine, plastics, and water treatment etc [2-3].
