在碳纳米管(CNT)上接枝烯丙基,将微量接枝后的碳纳米管(ACNT)加入到不饱和聚酯树脂(UPR)中制备出CNT/UPR和ACNT/UPR纳米复合材料。研究了纳米复合材料的电性能,结果表明:ACNT/UPR纳米复合材料的电性能明显优于CNT/UPR纳米复合材料的电性能。ACNT质量分数为0.075%时,ACNT/UPR纳米复合材料相对纯UPR的体积电阻率和耐电弧性有较大的提升,击穿场强略有增加,表面电阻率降低。
Carbon nanotubes (CNT) grafted allyl, the micro-grafted carbon nanotubes (ACNT) was added to the unsaturated polyester resin (UPR), the ACNT/UPR and CNT/UPR composite were produced. Electrical properties of composite were studied. The results showed that the electrical properties of ACNT/UPR composite was better than the electrical properties of CNT/UPR composite. When the dosage of ACNT was 0. 075% , volume resistivity and arc resistance of ACNT/UPR composite were greatly improved with respect to CNT/UPR composite, breakdown field strength slightly was slight increased, surface resistivity was decreased.
