Abstract

The invention discloses a graphene oxide coated hollow glass bead preparation method. The method comprises the steps of dispersing graphene oxide into deionized water to prepare a graphene oxide watersolution, putting hollow glass beads into the graphene oxide water solution to obtain dispersion liquid, and performing ultrasonic shaking treatment and drying treatment on the dispersion liquid at the same time to obtain graphene oxide coated hollow glass beads. By means of the ultrasonic shaking treatment and drying treatment on the dispersion liquid at the same time, the surfaces of the hollowglass beads can be evenly coated with the graphene oxide; thus, other additives of adhesives are avoided, and surface performance of the hollow glass beads is kept.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a preparation method of graphene oxide-coated hollow glass microspheres. Background technique [0002] Graphene oxide has good wetting properties and surface activity, and can be exfoliated after being intercalated by small molecules or polymers, which plays a very important role in improving the thermal, electrical, mechanical and other comprehensive properties of materials. Hollow glass microspheres have the characteristics of light weight, low density, and large surface area. They have important application values ​​and broad application prospects in the fields of energy, environmental protection, and biomedicine. Devices, drug controlled release capsules, etc. [0003] Graphene oxide-coated hollow glass microspheres, due to the presence of graphene oxide on the surface, greatly improve the electrical conductivity, further expanding the application field of hollow...
