The increasing demand for biodegradable materials in various fields has led to a growing interest in the development of hydrogels derived from natural polymers. Chitosan, a biocompatible and biodegradable polysaccharide derived from crustacean shells, is a promising material for the synthesis of hydrogels. The aim of this research is to investigate the synthesis of chitosan-based hydrogels by grafting from the chitosan backbone via RAFT polymerization, which is a suitable method for synthesizing chitosan-based hydrogels, as it allows for control over the molecular weight and the microstructure of the resulting hydrogel. The chitosan acts as a cross-linker, we anticipate that this design will allow us to have a larger mesh size and improve mechanical strength since the cross-linking sites are densely located at the chitosan backbone. By controlling monomer and chain transfer agent ratios, we explore the water swelling ratio and modulus of the synthesized hydrogels.
