NANODIAMOD AS A PECULIAR ADDITIVE TO IMPROVE TRIBOLOGICAL PROPERTIES OF POLYMER COMPOSITES

Polymers have been used in various forms such as bulk, films, and composites in applications where their scratch and wear resistance, surface chemical resistance and other surface-related properties have been effectively utilized. There are many examples in which polymers have performed extremely well, such as in tyres, shoes, brakes, gears, bearings, small moving parts in electronics and MEMS, cosmetics/hair products, and artificial human joints. Around the world, much research is currently being undertaken to develop new polymers, in different forms, for further enhancing tribological performance and for finding novel applications. Keeping in view the importance of tribology of polymers for research and technology, in this work diamond nanoparticles were used to enhance the Tribological properties of the PP/EPDM blend. Results of the Nanoscratching test revealed that presence of nanodiamond in this polymer matrix resulted in improvement of scratch resistant that led to smaller scratch dimensions and more interestingly, significant enhancement in defect recovery tendency of the diamond-based nanocomposite
