Abstract
AbstractIn this work, octadecyl trichlorosilane (ODTS) was used to modify the surface of graphene oxide. Further, varied concentrations of silane‐modified graphene oxide were used to make silicone rubber nanocomposite. The mechanical, thermal, and tribological properties of the composite were studied. The results showed that a small amount of silane‐modified graphene oxide significantly increased the mechanical and tribological performances. Under dry sliding, silane‐modified graphene oxide to the silicone matrix significantly reduced wear and friction properties. Nanocomposites have a lower wear rate than neat silicone rubber; their friction coefficient is almost 36% less than pure silicone rubber: the higher the load and temperature conditions, the more significant the difference in friction and properties. Wear mechanisms were revealed by scanning electron micrographs of the worn surface. The transfer film formation on the counter surface and acceptable wear debris improved the nanocomposites friction and wear resistance characteristics.
