摘要
采用浇铸法制备了不同含量多壁碳纳米管(MWCNT)的MWCNT/环氧树脂(EP)复合材料。用扫描电镜观察了MWCNT/EP复合材料的微观结构,发现MWCNT均匀分散在EP中。研究了MWCNT/EP复合材料的导电逾渗行为,材料的逾渗值为0.033%。分析了复合材料的动态力学性能,结果表明MWCNT的加入提高了EP的固化交联程度和韧性,同时复合材料的玻璃化转变温度也有提高。
The multi-walled carbon nanotube（MWCNT）/epoxy resin（EP） composites with different MWCNT content were prepared by using casting method. The micro-structures of the MWCNT/EP composites were observed by using scanning electron microscopy. It was found that the MWCNT was uniformly dispersed in EP. The conductive percolation behavior of the MWCNT/EP composites was investigated. The percolating value of the composites is 0.033%. The dynamic mechanical performance of the composites was analyzed. The results show that the curing cross-linking degree and the toughness of EP can be improved by addition of MWCNT, and the glass transition temperature of the composites also increases.
