单宁酸改性碳纳米管/羧基丁腈橡胶导热复合材料的性能研究

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。;The effects of tannic acid（TA） modified carbon nanotubes（CNT）（CNT-TA） on the properties of CNT/carboxyl nitrile butadiene rubber（XNBR） 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 be extended to the other polymer matrix thermal conductive composites
