Study on the Reinforcement Mechanism of Graphene Oxide for Non-asbestos Gasket Composites

抄録

To improve the quality of the gasket and reduce leakage, non-asbestos gasket composites reinforced by graphene oxide(GO) were prepared. The effect of GO on the microscopic physics and chemistry of slurry suspension and the macroscopic properties of gasket composites were investigated. The microstructure and morphology were analyzed by Fourier-transform infrared (FTIR) spectroscopy and Field emission scanning electron microscopy (FSEM). The results show that the addition of GO improves the microscopic interaction during the wet forming process, which improves the macro properties of the gasket material. The enhancement can be ascribe to the crumpled morphology of GO and the presence of many oxygen-containing functional groups, which enhance the microscopic mechanical interlocking and interfacial interactions of the composite gasket material.
