Abstract: Polyimide is a kind of polymer with excellent comprehensive performance.In this paper,titanate coupling agent was used to modify hexagonal boron nitride(h-BN),and we prepared the composites with raw h-BN and modified h-BN.Then,its performance was studied,the results showed that:with the increase of the content of h-BN,the thermal conductivity and thermal stability of composites were improved and the water absorption was declined.Furtherly,it was found that the properties of composites prepared with modified h-BN were better.
