A high-efficiency, non-toxic antibacterial composite material and its preparation method

Abstract

This invention belongs to the field of polymer composite material technology, specifically relating to a high-efficiency, non-toxic, and antibacterial composite material and its preparation method. It mainly comprises the following components by weight: 80-100 parts aliphatic polyamide, 5-15 parts toughening agent, 10-30 parts fiber-reinforcing filler, 6-12 parts nano-zinc oxide particles, 4-6 parts nano-montmorillonite, and 1-3 parts graphene oxide. This invention adds a certain amount of nano-zinc oxide particles, nano-montmorillonite, and graphene oxide. Nano-montmorillonite is a two-dimensional layered silicate that helps fix and disperse zinc oxide particles. Graphene oxide is rich in oxygen-containing functional groups and has a two-dimensional layered structure and a large specific surface area, which can promote dispersion and help zinc oxide achieve a finer particle size and more uniform distribution. This solves the problem of easy agglomeration of nano-zinc oxide particles, thereby greatly improving the mechanical properties and antibacterial ability of the composite material, making it suitable for use as a fiber fabric material.
