摘　　要：采用高色素气法炭黑作为遮光剂,亚微米级无定型二氧化硅作为消光剂,制备低光泽度黑色聚酰亚胺复合薄膜,探讨炭黑和二氧化硅掺杂对聚酰亚胺复合薄膜的遮光性、消光性、电气绝缘性、力学性能及表面形貌的影响。结果表明:黑色聚酰亚胺复合薄膜中炭黑掺杂量对遮光性和电气性能的影响最显著,二氧化硅掺杂量对光泽度的影响最明显;无机填料的总掺杂量越大、大颗粒填料占比越多的黑色聚酰亚胺复合薄膜力学性能越低;炭黑掺杂量4%、二氧化硅掺杂量5%时,光泽度可以控制在25 GU,光透过率接近0,同时具有良好的力学性能和电气性能。High color gas carbon black as a shading and submicron sized amorphous silica as a mat-ting were used to prepared a series of low-gloss black polyimide films.The effects of carbon black and silica doping on the light shielding,matting,electrical insulation,mechanical properties,and surface mor-phology of polyimide films were investigated.The results show that the doping amount of carbon black in the black polyimide composite films has the most significant influence on the light shielding and electrical properties,while the doping amount of silica has the most obvious effect on the gloss.The mechanical prop-erties of black polyimide films decrease with the increase of the total doping amount of inorganic fillers and the proportion of large particles.When the doping amount of carbon black is 4%and the doping amount of silica is 5%,the gloss could be controlled at 25 GU,the light transmittance is close to 0,and the films ex-hibit good mechanical and electrical properties and other comprehensive properties.
