Preparation and Swelling Characteristics of Hydrogel from Microbial Low Molecular Weight Poly(γ-Glutamic Acid)

In this paper, a novel low molecular weight poly (γ-glutamic acid) hydrogels were prepared by chemical method, and their preparation conditions such as poly (γ-glutamic acid) and crosslinker concentration, pH and temperature were studied. When poly (γ-glutamic acid) solution was 18%, pH 4.0, poly (γ-glutamic acid) was crosslinked to yield high water hydrogel with specific water content of 1328 times their dry volume depending on the preparation conditions.
