  • Title: Preparation and characterization of pH-sensitive hydrogel of chitosan/poly(acrylic acid) co-polymer.
    Author: Shi L, Yang L, Chen J, Pei Y, Chen M, Hui B, Li J.
    Journal: J Biomater Sci Polym Ed; 2004; 15(4):465-74. PubMed ID: 15212329.
    Abstract:
    A pH-sensitive co-polymer hydrogel of chitosan/poly(acrylic acid) (CS/PAAc) was prepared by irradiating the aqueous solution mixture of chitosan and acrylic acid with 60Co gamma-ray irradiation. The effect of the composition of chitosan and AAc on the properties of the hydrogel, such as swelling ratio and pH-sensitivity, were determined. Fourier Transform Infrared (FT-IR) spectrometry was applied in the attenuated total reflectance (ATR) mode for analyzing the structure change of the hydrogels after the treatment in different pH buffer solutions.
