| titleOfInvention | Method for preparing chitosan oligosaccharide modified biodegradable composite |
| abstract | The invention mainly relates to a method for preparing a chitosan oligosaccharide modified biodegradable composite. The method comprises the steps of: firstly, with N,N-dimethyl formamide as a solvent, protecting amino of chitosan oligosaccharide by using phthalic anhydride to prepare a N-methyl o-acyl chitosan oligosaccharide reaction intermediate; secondly, dropwise adding pyridine solution of stannous octoate under protection of nitrogen, initiating an epsilon-caprolactone monomer to carry out ring opening polymerization so that polycaprolactone is grafted on hydroxyl of N-methyl o-acyl chitosan oligosaccharide, so as to generate a chitooligo saccharide-grafted polycaprolactone thermoplastic material; and finally melting and blending LDPE (low-density polyethylene), chitooligo saccharide-grafted caprolactone and polycaprolactone to prepare the biodegradable composite. The blended composite has biological degradability, and is free of poison and wide in application range; deterioration of an ecological environment is effectively improved; and the situations of energy crisis and petroleum resource shortage are solved. |
