Developing tendency of increasing integration in electronic components filed led to the demand for thermally conductive polymer materials. Forming a segregated structure with thermally conductive fillers in the matrix has been proven to be a promising technique. However, the mechanical properties of the material prepared via this technique are commonly sacrificed because the interaction between fillers and matrix are weak. We present a simple method to improve the mechanical properties while maintaining the segregated structure via the collaboration of epoxy and polybenzoxazine(PBz). The fillers, epoxy resin, and benzoxazine(BOZ) were mixed and then hot pressed under 12 MPa of pressure with a certain heating strategy. The thermal conductivity, density, mechanical properties, morphology, and thermal stability of the composites were investigated. With 25 wt% filler, the value of thermal conductivity coefficient of EP/PBz composites reached 0.811 W mK −1 , while that of PB...

通过掺入环氧树脂和隔离结构改善聚苯并恶嗪复合材料的导热性和机械性能

电子部件中集成度的增长趋势导致对导热聚合物材料的需求。已经证明在基质中用导热填料形成隔离结构是一种很有前途的技术。但是，由于填料和基体之间的相互作用较弱，因此通常会牺牲通过该技术制备的材料的机械性能。我们提出了一种简单的方法来改善机械性能，同时通过环氧树脂和聚苯并恶嗪（PBz）的协作保持隔离的结构。混合填料，环氧树脂和苯并恶嗪（BOZ），然后在一定压力下以12 MPa的压力进行热压。研究了复合材料的热导率，密度，机械性能，形态和热稳定性。
