中文摘要: |
研究单宁酸(TA)改性碳纳米管(CNT)(CNT-TA)对CNT/羧基丁腈橡胶(XNBR)导热复合材料性能的影响。结果表明:采用TA对CNT进行非共价键改性可以显著提高CNT在XNBR基体中的分散性,CNT-TA/XNBR复合材料比CNT/XNBR复合材料具有更好的力学性能、介电性能和导热性能;CNT-TA可以应用到其他聚合物基导热复合材料中。 |
英文摘要: |
The effects of tannic acid(TA) modified carbon nanotubes(CNT)(CNT-TA) on the properties of CNT/carboxyl nitrile butadiene rubber(XNBR) thermal conductive composites were studied.The results showed that the dispersion of CNT in XNBR matrix could be significantly improved by using TA to modify CNT with non-covalent bond. Compared with CNT/XNBR composites,CNT-TA/XNBR composites showed better mechanical property,dielectric property and thermal conductivity. CNT-TA could also be applied to prepare thermal conductive composites with other polymer matrix. |
