摘要/Abstract

摘要： 环氧树脂由于固化后呈现出三维交联网络结构,导致其耐磨性能较差,限制了其广泛应用。为了克服上述缺点,本文主要研究了功能化碳纳米管的加入和表面化学复合镀对环氧树脂复合材料摩擦磨损性能的影响。研究发现,添加0.5wt%的胺基化碳纳米管/环氧树脂复合材料的摩擦系数和磨损率分别为0.314和0.93 × 10^-4 g·min^-1。与纯的环氧树脂相比,其磨损率降低了41.3%。因此,碳纳米管的加入可以有效的降低环氧树脂的摩擦系数和磨损率。与此同时,通过表面化学复合镀技术在复合材料表面涂覆Ni-P-CNTs 复合镀层,Ni-P-CNTs 镀层进一步起到了减磨耐磨的效果。因此,将碳纳米管添加到环氧树脂中和表面化学复合镀技术相结合是一种有效的提高环氧树脂耐磨性的方法。

Abstract: Epoxy resin curing presents 3D cross-linking network structure characteristics,resulting in epoxy resin displaying a lower wear resistance,which limits its extensive applications. To overcome this disadvantage,in this paper,the effects of adding carbon nanotubes into epoxy and electroless plating on friction and wear behavior of epoxy-based composites were studied. The results showed that the friction coefficient and wear rate of the epoxy composites with 0.5wt% amino-MWCNTs are 0.314 and 0.93×10^-4 g·min^-1,respectively. Compared with the neat epoxy,its wear rate decreased by 41.3%. Thus,the friction coefficient and wear rate were effectively decreased by adding carbon nanotubes into epoxy and the wear resistance was improved. Meanwhile,Ni-P-CNTs composite coating was brought into epoxy composites surface by electroless plating. It was found that Ni-P-CNTs coating further decreased the wear rate of composites. Thus,combining the addition of carbon nanotubes with electroless plating technology is an effective method to improve the wear resistance of epoxy-based composites.

Key words: epoxy, carbon nanotube, electroless plating, friction and wear behavior
