Progress on the Influence of Four Inorganic Nanoparticles on the UV Resistance of Plastics

Inorganic nanoparticles have always attracted much attention in the research of plastic UV resistance.This article mainly introduces the application of four typical inorganic nanoparticles(TiO₂,ZnO,SiO₂,CeO₂)in this field.Firstly it summarizes its anti-ultraviolet mechanism that can absorb,reflect or scatter ultraviolet rays;secondly,it discusses the applicable ultraviolet wavelength range of different inorganic nanoparticles,focusing on the addition methods and application characteristics of plastics.The research status and progress of four kinds of inorganic nanoparticles in the anti-ultraviolet properties of plastics at home and abroad are reviewed.Finally the application characteristics of the four kinds of inorganic nanoparticles in the anti-ultraviolet properties of plastics are compared,and the dispersion and progress in the application process are proposed.Problems such as poor compatibility are expected to provide a certain reference for the in-depth application and development of inorganic nanoparticles.
