摘要
用紫外光辐照法制备了反式-1,4-聚异戊二烯(TPI)/碳纳米管(CNTs)复合材料,研究了复合材料的导电性能和电磁性能。结果表明,室温下,当CNTs质量分数为5%时,复合材料的体积电阻率比纯TPI下降了7个数量级,达到6.07×108Ω.cm;当温度为20~100℃时,复合材料的电导率基本保持稳定。在2~10GHz的微波频段内,复合材料的介电损耗远远大于磁损耗,具有较宽的介电损耗(约为21~48)。
Composites of trans-1,4-polyisoprene/carbon nanotuhes(TPI/CNTs)were prepared using an ultraviolet. The electric conductivity and electromagnetic property of TPI/CNTs composites were studied. The results showed that the bulk resistivity of composites decreased by 107 times to 6.07×108 Ω·cm with adding mass fraction of 5% of CNTs. The conductivity of the composites almost kept stable in 20~100 ℃. In 2~10 GHz of microwave, the dielectric loss were much larger than magnetic loss of the composites, to 21~48.
