| 中文摘要: |
| 通过动态硫化法制备一维多壁碳纳米管（MWCNTs）增强丁基橡胶（IIR）/聚丙烯（PP）热塑性弹性体（TPV）复合材料，研究IIR/PP用量比（简称橡塑比）对复合材料相态结构、介电性能、导热性能和物理性能的影响。结果表明：复合材料呈现“海岛”相结构，IIR相以微米级交联颗粒分散在PP相中；MWCNTs主要分散在PP中，随着橡塑比的增大，MWCNTs有少量团聚现象；随着橡塑比的增大，复合材料的交流电导率、介电常数和热导率增大，且橡塑比大于6/4时增速减小；随着橡塑比的减小，复合材料的拉伸强度先增大后减小；当橡塑比为5.5/4.5时，复合材料的物理性能较好。 |
| 英文摘要: |
| The one-dimensional multi-walled carbon nanotubes（MWCNTs） reinforced butyl rubber（IIR）/polypropylene（PP） thermoplastic elastomer（TPV） composites were prepared by dynamic vulcanization method.The effects of IIR/PP dosage ratio（rubber/plastic ratio） on phase structure，dielectric property，thermal conductivity and physical properties of composites were studied.The results showed that the composites had an “island” structure，and the IIR phase was dispersed in PP phase as micron crosslinked particles.MWCNTs were mainly dispersed in PP，and began to agglomerate with the increase of the rubber/plastic ratio.The AC conductivity，dielectric constant and thermal conductivity of the composites increased with the increase of the rubber/plastic ratio，and the increase rate decreased when the rubber/plastic ratio was above 6/4.With the decrease of the rubber/plastic ratio，the tensile strength of the composites increased first and then decreased.When the rubber/plastic ratio was 5.5/4.5，the physical properties of the composites were better. |
