Description

Sustainable biomaterials, including diverse types of polysaccharides, are the most abundant raw materials on earth. Despite of extensive research on their biological synthesis and molecular structures, understanding of their particular structure constructions, physicochemical properties and further application in the field of advanced technology still need much more exploration. For these purposes, the chemical derivatisation by introducing diverse functional groups is a promising way for the adjustment of their physicochemical properties and for expanding their application areas. In particular, a few polysaccharides can be present as polymeric chains or as crystalline supramolecular structures, which not only require totally different methodologies for the modification but also provide opportunities for distinct functions. During further preparation of diverse functional materials by combining with synthetic polymers and other compounds, diverse novel structures via self-assembly are achieved and novel physicochemical properties are observed. Thus, native sustainable biomaterials, with the polysaccharides as the most abundant group, demonstrate a great platform for high-performance functional materials after chemical modification and precise material design. Moreover, due to their particular structures, specific properties accompanying the materials there derived can be observed in comparison to other polymeric systems.
