Abstract

High volume fraction carbon nanotube (CNT) composites (7.5-16% vol.) were fabricated by the impregnation of CNT buckypapers into epoxy resin. To enhance the interfacial reaction with the epoxy resin, the CNTs were modified by two different treatments, namely, an epoxidation treatment and a chemical oxidation. The chemical treatment was found to result in CNT length severance and to affect the porosity of the buckypapers, having an important impact on the physico-mechanical properties of the nanocomposites. Overall, the mechanical, electrical, and thermal properties of the impregnated buckypapers were found to be superior of the neat epoxy resin, offering an attractive combination of mechanical, electrical, and thermal properties for multifunctional composites.

摘要

通过将碳纳米管（CNT）巴基纸浸渍到环氧树脂中，制备了高体积分数的碳纳米管复合材料（体积分数为7.5 - 16.16%）。为了增强与环氧树脂的界面反应，对碳纳米管进行了两种不同的处理，即环氧化处理和化学氧化。发现化学处理会导致碳纳米管长度缩短，并影响巴基纸的孔隙率，这对纳米复合材料的物理机械性能有重要影响。总体而言，发现浸渍后的巴基纸的机械、电气和热性能优于纯环氧树脂，为多功能复合材料提供了有吸引力的机械、电气和热性能组合。
