摘要
Epoxy-based nanocomposites containing functionalized nanoscale TiO2 with 0.5%, 1%, 5%, and 10% by weight were developed. A coupling agent was employed to functionalize nano titania for better compatibility of nanoscale particles with dispersing media. Under sliding conditions, the specific wear rate and coefficient of friction were evaluated. The dispersion of fillers in the matrix was also studied using scanning electron microscopy. The wear mechanism is studied in correlation with a micrograph of the worn-out surface of nanocomposites. The various mechanical properties and thermal stability were studied and the influences of nanofiller loading on these parameters were observed.
