摘要
The effect of multi-walled carbon nano tubes on the hardness, friction and wear of polymethyl methacrylate reinforced by MWCNTs of 0.1, 0.2, 0.3, 0.4 and 0.5 wt. % contents is investigated. PMMA is prepared at both hot and cold acrylic resins to be used as denture base materials. Wear of hot composites decreased by increasing MWCNTs content up to 0.3wt. % and then increased, while wear of cold composites increased by increasing MWCNTs content. Friction coefficient of hot and cold composites decreased by increasing MWCNTs content and it was affected by the normal load.
