Preparation of polyimide composites reinforced with oxygen doped boron nitride nano-sheet as multifunctional materials

In this article, oxygen doped boron nitride (OBNNS) was selected and introduced into PI to form OBNNS/PI composite films. The thermal, electrical, optical and mechanical properties of the OBNNS/PI composite films were all improved compared to pure PI. Our experimental results shown that the synthesi...
