由生物质合成环境友好材料及其生物降解动力学研究

An environmental friendly material with high intensity water resistance biodegradability and antibacterial activity was designed and synthesized via biomass: chitosan, starch, konjac glucomannan blending assembly, surface modification, cross-linking, enzymolize, interpenetrating polymer network (IPN) with other biomacromolecule: cellulose, glutin, soy protein et al. According to the analysis of FT-IR, XRD, NMR, SEM, DTA, HPLC, PALS and EPMA, the nature of the non-covalent interaction: hydrogen bond, electrostatic attraction, ionic bond between nature polysaccharide and biomacromolecule, the mechanism of the interfacial bonding of hydrogen bond and covalent bond, and the rule of the supramolecular aggregate and disaggregate were discussed initially. The innovations of this study are the innocuitify of the biomass polymer material, the solution blend transform and enzymatic techniques which were advantageous to the formal polymerize and dispolymerize techniques, and the novel polymer and depolymer were not only the biomaterial with some funtions, but also could reveal the scalar correlation of material's structure and capability, which had diverse appliances. The applications of chitosan complex as packing material and medicine are on study.
