    • In accordance with the present teachings, there are composite materials, fuser members comprising the composite materials, and methods of making the composite materials. In various embodiments, the composite material can include a polyimide resin having a thermal conductivity and a plurality of passivated aluminum nitride particles substantially uniformly dispersed in the polyimide resin to provide the composite material with a thermal conductivity of 0.4 W/mK to 2.5 W/mK, and wherein each of the plurality of passivated aluminum nitride particles can include a passivation layer disposed over an aluminum nitride particle core to inhibit oxidation and thermal degradation of a surface of the aluminum nitride particle core.
    • 根据本教导,存在复合材料,包含复合材料的定影器构件以及制造复合材料的方法。 在各种实施方案中,复合材料可以包括具有导热性的聚酰亚胺树脂和基本上均匀分散在聚酰亚胺树脂中的多个钝化的氮化铝颗粒,以使复合材料的导热率为0.4W / mK至2.5W / mK 并且其中所述多个钝化氮化铝颗粒中的每一个可以包括设置在氮化铝颗粒芯之上的钝化层,以抑制氮化铝颗粒芯的表面的氧化和热降解。
