%0 Journal Article %T State of Art Review on Tribology of Carbon Nanotubes Filled Polymer Nanocomposites %A Mohammed Fahim %J Journal of Scientific Review %D 2011 %I Scientific Review Board %X Development and tribological characterization of polymer nanocomposites, derived from carbon nanotubes (CNTs) filled tribologically significant engineering polymers, is a growing area of research in tribology. This is based on the preliminary investigations that show CNTs as a promising filler to enhance friction and wear performance of base polymers. However, the research is still in the formative stages and more work needs to be done to resolve three major issues that challenge the optimum utilisation of the properties of CNTs. Firstly, deagglomeration of CNTs and their uniform dispersion in the polymer matrix is a big challenge. Secondly, the interaction of CNTs with polymer matrix needs to be improved using proper functionalization of the former. In fact functionalised CNTs have been explored, the preliminary results, however, have not been very encouraging. Thirdly, the mass production of such composites using industrial moulding processes poses another challenge. This overview presents the state of the art review of research papers available on the subject. It has been observed that the role of CNTs in influencing the wear and friction behaviour, either as lubricating wear debris or as abrasives is still debatable and remains a major issue that needs to be resolved. %K Carbon nanotubes %K polymer nanocomposites %K tribology %K sonication %U http://www.srbmag.org/index.php/srbmag/article/view/126
