Abstract

Abstract: To expand the application of multi-layer graphene in water-based systems, modified multi-layer graphene was prepared by vacuum impregnation with silica sol and carbon-embedded heat treatment at 300, 500 or 700 °C for 3 h. The phase composition, microstructure and wettability of the modified multi-layer graphene heat treated at different temperatures were studied. The results show that the water wettability of the modified multi-layer graphene is improved after vacuum impregnation with silica sol and carbon-embedded heat treatment; the optimum heat treatment temperature is 300 °C, and the modified multi-layer graphene has the water wetting angle of 64.7°.

Key words: multi-layer graphene, surface modification, silica sol, vacuum impregnation method, wetting angle
