Abstract

The invention discloses a cellulose acetate nano composite material with ultraviolet shielding and bacteriostatic properties and a preparation method thereof. The cellulose acetate nano composite material is composed of the following components by weight: 96-99.5 parts of cellulose acetate and 0.5-4 parts of copper complex modified halloysite. The copper complex modified halloysite is used as a modifier, so that the performance of the cellulose acetate can be effectively improved. The cellulose acetate nano composite material prepared by the invention has excellent ultraviolet shielding performance, bacteriostatic performance, thermal stability, water vapor barrier property, low hygroscopicity and low cytotoxicity, can keep high optical transparency, and is simple in preparation process, environment-friendly, low in cost, suitable for large-scale production, and has good application prospects in the fields of packaging, ultraviolet protection and the like.
