Abstract
Chitosan is a natural polysaccharide constituted by N-glucosamine and N-acetyl glucosamine. It has many inherent characteristics, including carrying amino groups. Taking advantage of these unique characteristics, chitosan-based materials were improved and diversified: n the first part, a straightforward method has been developed for chitosan material; this method does not result in a brittle product, thus making it better than the use of toxic cross-linking reagents such as glutaraldehyde. In the second part, novel composite porous membranes were developed. Such composite membranes had outperformed the traditional chitosan materials and have potential. In the third part, several plasticizers were incorporated with chitosan. They could be good choices for future development of chitosan-based materials.iversification is important for the applicability of a material. The greater the diversity of a material, the higher probability it would be successfully used in specific applications.
