摘要

多壁式奈米碳管(multi-walled carbon nanotube,MWCNT)目前已被廣泛的應用在各種高科技產業之中，因具有特殊的管狀結構，當不同含量比率的奈米碳管，均勻的分佈在基材中，除了能強化基材的機械性質外，也能夠提供兩種不同接觸界面的潤滑效果，進而降低摩擦係數及提升抗磨耗性，減少磨耗產生。然而一般研究大多都只是探討一種複合材料的磨耗特性，甚少同時以不同高分子基材之複合材料去做研究，且傳統多壁式奈米碳管複合材料之製程極為繁複，必需利用兩次熔融攪拌製程才能得到奈米碳管分散效果較佳之複合材料，故為簡化奈米碳管複合材料製程，本研究改以高分子粉末直接攪合多壁式奈米碳管製程，使得製程簡化且可提升分散效果，製作出不同高分子基材之複合材料，並透過磨耗機台(Pin on Disk)進行磨耗實驗，探討不同高分子基材添加奈米碳管強化後對其耐磨性質之影響。

Multi-walled carbon nanotube(MWCNT) have now been widely used in various high-tech industries, because of a special unmatched topological hollow tubular structure. When the ratio of different content of the Carbon nanotubes, evenly distributed in the matrix, it can reinforce the mechanical nature of the matrix, and also provide two different interface of lubricating effect. Thereby reducing friction coefficient and enhance anti-wear to decrease the wear. But most research just general research on composites of wear characteristics, rarely research in different high molecular matrix of composite materials at the same time. And the traditional carbon nanotubes in composite materials is extremely complicated process, the necessary use of two melt mixing process can be better dispersion effect of carbon nanotubes composite materials. So to simplifying carbon nanotubes composite process, this research replace with powder directly to blend so as to simplify the process and increase dispersion. At this rate to produce different high molecular matrix composites, and through the wear bench(Pin on Disk) to carry through the wear experiment. The tenet is to probe into the wear-resistant effect difference of high molecular matrix reinforcement after add on carbon nanotube.
