Good tribological properties can be obtained for polymers filled with nano-scale fillers compared to that filled with micro-scale particles. The friction and wear resistance of these composites is found to increase with increasing filler concentration. It is also possible to use multi-functional fillers to develop high performance composites which cannot be achieved by using a single filler. %K Friction %K Wear %K Polymer Composites %K Nano-Particles %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=18162
