Abstract

Investigation on the effect of nano-silica on the effect of nano-silica on the surface morphology and mechanical properties has been carried out on two-dimensional (2D) gradient polymer-silica composite samples varied in chemical composition (e.g., filler size/concentration). A combination of techniques including nanoindentation and laser scanning confocal microscopy was utilized to measure surface modulus and roughness, and map scratch damage patterns. Preliminary results show the addition of nano-silica reduces surface roughness, increases modulus and hardness, and improves scratch resistance of the polymer-silica composite systems.
