Cyclic Nanoindentation and Nano-scratch Behaviour of CaCO3/PMMA Nanocomposite
Abstract: The calcium carbonate surface modified with γ-methacryloxypropyltrimethoxysilane was carried out to prepare poly (methyl methacrylate) based composite. The grafting of PMMA increased as the weight ratio between MMA and n-CaCO3 increased, while the grafting efficiency of PMMA decreased. Transmission electron micrograph showed that MPTMS modified n-CaCO3 covered with PMMA was formed by emulsion polymerisation. The scratch resistance of n-CaCO3/PMMA nanocomposites are highly influenced by reinforcement’s type. The effects of n-CaCO3 …
