摘　　要：以聚醚醚酮(PEEK)为基体,碳纳米管(MWNTs)、羟基化碳纳米管(MWNTs-OH)、羧基化碳纳米管(MWNTs-COOH)为添加剂,通过熔融共混、模压成型的方法制备了3种不同的PEEK/MWNTs复合材料,通过热重分析法、锥形量热法对复合材料的热稳定性、阻燃特性进行研究。结果表明:纯聚醚醚酮材料比碳纳米管/聚醚醚酮试样容易点燃;羧基化碳纳米管/聚醚醚酮试样相比于其他的试样拥有更低的平均释放速率和热释放速率峰值(PHRR),PHRR较单纯的聚醚醚酮降低了16%;初始氧化温度达到507℃,具有较好的热稳定性。Three different kinds PEEK/MWNTs composite were prepared by melt blending and compression molding with PEEK as matrix and MWNTs, MWNTs-OH, MWNTs-COOH as additive. Thermo gravimetric analysis （TGA） and cone calorimetry were used to evaluate the thermal stability and retardant properties of the composite. The results showed that pure PEEK was easier to ignite than PEEK/MWNTs composite. Compared with other samples, PEEK/MWNTs-COOH sample had lower average release rate and peak heat release rate, PHRR was reduced 16% comparing with pure PEEK, initial mass loss temperature of the samples was up to 507 ℃ and had better thermal stability.
