Title:
COPPER-MODIFIED GRAPHENE OXIDE-BASED COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/027115
Kind Code:
A1
Abstract:
The present invention provides a preparation method for a copper-modified graphene oxide-based composite material, comprising the following steps: A) mixing a copper salt and a graphene oxide dispersion liquid, and performing ultrasonic dispersion to obtain a mixed solution; B) evaporating the mixed solution to dryness so as to obtain powder; C) performing thermal treatment on the powder at 50-400°C for 5-24 hours to obtain thermally treated powder; D) reducing the thermally treated powder in a hydrogen-containing atmosphere to obtain reduced powder; and E) in a vacuum environment, performing spark plasma sintering on the reduced powder to obtain a copper-modified graphene oxide-based composite material. According to the present invention, a novel light-specific-gravity graphene-based composite material combining a plurality of excellent performance such as high strength, abrasion resistance, and a low friction coefficient can be prepared. The present invention further provides a copper-modified graphene oxide-based composite material and a use thereof.
