Abstract

The invention discloses a preparation method of nano-scale micron-scale multistage-structure composite glass fiber. In the preparation process, firstly, the surface of the glass fiber is coated with a layer of graphene oxide, so that the fiber structure can be effectively protected, and damage of a strong oxidizing environment, a strong alkaline environment and the like on the structure and the performance of the glass fiber is avoided; meanwhile, a nanometer material grown on the surface of the glass fiber not only increases the surface roughness of the glass fiber, but also increases the specific surface area of the glass fiber. In the preparation process of coating the glass fiber with the graphene oxide, the conventional physical adsorption as well as the electrostatic effect between positive and negative charges is utilized, so that the graphene oxide coats the glass fiber more firmly. The nano-scale micron-scale multistage-structure composite glass fiber prepared by the preparation method is good in severeness resistance and alkali corrosion resistance, has a stronger interface bonding force with a matrix, and is contributive to development of high-performance concrete.
