摘　　要：采用原位聚合法,通过熔融共聚制备了HBA/HNA-GO液晶聚酯复合材料。研究了不同添加量的氧化石墨烯对纳米复合材料形态、结构和性能的影响。通过对复合材料的研究发现,氧化石墨烯的添加不会破坏TLCP原有的微观结构,且能够提高HBA/HNA液晶聚酯的热稳定性,为进一步研制高性能热致液晶聚芳酯提供了一个很好的方向。In this work, HBA/HNA-GO composite was prepared by melt polycondensation via in situ polymer-ization, and the effects of GO contents on the structure and properties of composites were studied.The results proved that microcosmic texture of HBA/HNA copolyester still existed and thermal stability of HBA/HNA copolyes-ter was enhanced with the increase of GO content.The work provides a good direction to further the development of high performance TLCPs.
