METHOD FOR THE PREPARATION OF SILVER NANOPARTICLES-POLYMER COMPOSITE

摘要

It is desired to develop a new composite composed of silver nanoparticles and a polymer in which silver nanoparticles are uniformly incorporated without coagulation in a polymer in order to maximize the antibacterial effect of silver without deteriorating the properties and functions of the polymer. According to the invention, a method for the preparation of silver nanoparticles-polymer composite comprising introducing silver nanoparticle colloid solution to a preheated polymer, rotating the resulted mixture at the same temperature to remove water, kneading and extruding the resulted mixture in a suitable form. The silver nanoparticle-polymer composite thus prepared can be used as a master batch or a functional chip for extrusion, injection, spinning to prepare molding article, film, sheet, fiber or the like.
