Synthesis and Characterization of a Novel Polysaccharide-based Self-healing Hydrogel
Polysaccharide-based hydrogels have attracted great interest for potential industrial and biomedical applications. However, the structural and functional integrity of hydrogels are often compromised by external mechanical forces or chemical degradation. This paper reports the fabrication of a self-healing hydrogel composite consisting of an oxidized xanthan gum (OXG) and chitosan (CS). Fourier transform infrared (FT-IR) spectroscopy showed successful formation of Schiff base bonding between CS and OXG. The hydrogels successfully self-healed at room temperature and pressure without any external stimulus such as water, pH level, and increase in temperature. A weight ratio of 1:1 (CS:OXG) results in a good balance between the self-healing capability and the mechanical strength of the prepared hydrogel.
