摘　　要：用溶液共沉析的方法制备了含二氮杂萘结构的聚芳醚酮 /钛酸钾晶须复合材料。晶须表面用偶联剂处理。研究了复合材料的拉伸强度、冲击强度、弯曲强度、形态及热性能。结果表明 ,复合材料的冲击强度和弯曲强度随晶须含量的增加而提高 ,而拉伸强度却呈下降趋势。热重分析显示 ,随晶须含量的增加 。Poly(phthalazinone ether ketone)/potassium titanate whisker composites were prepared by coprecipatation from solution.The whisker surface was modified using a coupling agent.The tensile strength,impact strength,flexural strength,thermal properties and morphology of the composites were investigated.Results showed that the impact and flexual strength of the composites increased with increasing whisker contents.However,the tensile strength of the composites decreased with increasing whisker contents.Thermogravimetric analysis showed that heat resistance of the composites tended to increase with increasing whisker contents.
