| 摘 要： | 研究氮化硼表面改性及其对氮化硼/硅橡胶复合材料热性能的影响。结果表明:活化可以提高氮化硼表面接枝率,偶联剂CA1对氮化硼的改性效果优于偶联剂KH570;随着氮化硼用量的增大,氮化硼/硅橡胶复合材料的热导率增大;加入氮化硼的复合材料热稳定性提高,但改性氮化硼/硅橡胶复合材料的热稳定性下降。

| Abstract: | Hexagonal boron nitride (h-BN) nanosheet is a novel high thermal conductivity and high aspect ratio filler that has the potential to substantially enhance the thermal conductivity of polymer composites.In order to increase the dispersion of BN in the matrix,the surface treatment of BN were coated by a silane coupling agent.Firstly increase the amount of surface functional groups of BN through activating the surface of boron nitride,then treat the surface of BN with a coupling agent .BN / SiR composites is prepared using a double planetary vacuum mixer.In this article,the activating and grafting of BN were studied,the influences of process to surface modification of BN was also investigated.Results showed that modification process and the surface of the graft have a great impact on BN. the surface of BN also affect thermal properties of composites, |
