Abstract

The invention relates to a synthesis method of metal nanometer particle and polysaccharide polymer composite material, which comprises subjecting solid phase polysaccharide polymers to oxidation reduction reaction in complex solution of liquid phase metal salt, reducing metallic ions in the solution into metallic atoms under the action of reducing agent, coordinating with hydroxyl on the polysaccharide polymer and and growing into atom clusters and nano particles. The physical chemical properties of the polysaccharide polymers can be substantially improved.

Description

technical field [0001] The invention relates to a method for synthesizing composite materials of metal nanoparticles and polysaccharide polymers. Background technique [0002] Polysaccharide polymers, especially polysaccharide polymers with cellulose structure, generally have poor comprehensive performance in use, and their applications are greatly limited. Contents of the invention [0003] The object of the present invention is to provide a method for synthesizing metal nanoparticles and polysaccharide polymer composite materials that can greatly improve the performance of polysaccharide polymers, especially polysaccharide polymers with cellulose structure. [0004] The present invention is realized by following process: [0005] The solid-phase polysaccharide polymer undergoes oxidation-reduction reactions in the complex solution of the liquid-phase metal salt: the metal ion in the solution (represented by M in the chemical formula, the same below), in the reducing age...
