A study on nanoindentation and tribological behaviour of multifunctional ZnO/PMMA nanocomposite

摘要

This work aims to compare the scratch hardness with the indentation hardness of ZnO nanoparticle reinforced polymethylmethacrylate (ZnO/PMMA) composites obtained from nanoindentation measurements. 50 μm thick films ZnO/PMMA nanocomposites were produced by the in-situ spin coating method. Scratch hardness was measured from the scratch width origin at low load during the course of the scratch measurements. A good correlation was found between the scratch hardness and the indentation hardness at low indentation depth, where a linear relationship between hardness and the reinforcement content of ZnO nanoparticles was observed. The composite was structurally established by transmission electron microscopy and furrier transform infrared spectroscopy.
