报告摘要：

Sustainable biomaterials represent the most abundant raw materials on earth. A vast group of them is polysaccharides, which include cellulose, chitin and starch. Rather than monosaccharides, polysaccharides and their supermolecular structures provide readily applicable platforms for functional nanomaterials. Herein, novel functional nanomaterials derived from diverse sustainable biomaterials with smart and stimuli-responsive properties will be presented. Chemical modifications demonstrate great tools for the functionalization, which leads to specific materials with particular material performance after further physical treatments. In addition, novel physicochemical properties of these polysaccharides will be discussed based on these functional materials.
