In order to improve the wear resistance and service life of the epoxy resin (EP)-bonded diamond abrasive tools, graphene oxide (GO) was incorporated through a green method without any organic solvents. A curing accelerator, 3-methyl-N,N-diethylbenzenamine (3-MBDEA) acts as a phase transfer agent which rapidly catches GO from water phase to epoxy phase, and the diamond/GO/EP abrasive tools were fabricated via in situ polymerization. The effect of GO on the structure of EP was characterized, and the grinding performances of as-prepared diamond/GO/EP abrasive tools were evaluated in the grinding of concrete. Results show that the service life of the diamond/GO/EP abrasive tools are significantly improved by the incorporation of GO. In the case of the diamond with the size of 50 mu m (D50)/GO0.5/EP abrasive tool only with 0.5 wt% GO, its service life increases by 75% compares to that of the D50/EP abrasive tool. The excellent performance of diamond/GO/EP abrasive tools is attributed to the improvement of the wear resistance of EP and the enhancement of the interfacial adhesion between EP and diamond with the addition of GO. This work may provide a potential industrial application for graphene-related materials.
