  • 摘要: 随着碳纤维(CF)需求量的增加,CF边角料急剧增多,造成了极大的资源浪费。为解决这一问题,采用抽滤法将CF边角料制备成短切碳纤维(SCF)毡,以碳纳米管(CNT)作为二次填料,通过真空热压工艺制备了CF边角料增强热塑性聚氨酯(TPU)纳米复合电热材料(CNTx-SCF/TPU)。通过SEM、TGA、DSC等对复合材料进行测试分析,探究了CNT的最佳浓度,研究了 CNTx-SCF/TPU复合材料的力学性能和电热性能等。结果表明:采用克重为 60 g/m2的 SCF毡、CNT浓度为1.0 g/mL时制备的CNT1.0-SCF/TPU复合材料具有最高的电导率,达到417.84 S/m,与不添加CNT的SCF/TPU相比其电导率提高了34.78%;CNT1.0-SCF/TPU复合材料在3.5 V低电压下,240 s内即能达到约165℃的高温,具有优异电热性能,并具备电热温度可控、电热性能稳定等优点。
