Method for carbon fiber surface modification of plasma coated with silicon dioxide by plasma treatment

Abstract

The invention relates to a method for modifying the surface of carbon fiber coated with nano dioxide sol through plasma treatment, which comprises the following steps: firstly, nano silicon dioxide is prepared into an organic solvent, a sol solution of water or a sol solution prepared by hybridization reaction of a precursor solution of organic-inorganic nano particles and silicon dioxide nano particles by the ultrasonic vibrating technology; secondly, the sol solution is coated on the surface of the carbon fiber, treated by means of spray coating or padding and so on, and dried; and thirdly, the carbon fiber is placed on a plasma transport unit and a plasma is sprayed on the surface of the carbon fiber to generate modification, wherein the treating power is between 10 and 15,000 watts, and the treatment time is between 0.5 and 300 seconds. The method can effectively improve the performance of the carbon fiber, improves the molded manufacturability and the overall properties of composite materials of the carbon fiber, has simple technology, quick processing speed, good treatment effect and low cost, is convenient to operate and difficult to cause environmental pollution, can reduce energy consumption, and is suitable for industrial production.
