将载流子产生与传输功能集成到一层的高性能正电性薄膜器件是新型激光有机光导体的发展趋势.由于成膜树脂、传输材料分子和载流子产生材料粒子之间的相互作用,使得成膜之前的分散体系极易团聚而产生沉降现象,导致光导器件的性能劣化.本文以聚苯乙烯-丙烯酰胺(PSAM)、聚苯乙烯(PS)、聚乙烯吡咯烷酮(PVP)和硬酯酸酰胺(SR)分别在二氯乙烷中对Y-酞菁氧钛(Y-TiOPc)粒子进行表面处理,获得稳定的分散体系,然后再与溶解空穴及电子传输材料的聚碳酸酯二氯乙烷溶液混合得到有机光导材料分散液.通过测试Y-TiOPc的粒径、ξ电位、光透过率和反射率,以及原子力显微成像分析等袁征分散体系的稳定性.结果表明,采用该方法可获得长期稳定的PSAM@Y-TiOPc/TPD-m-TPD/DMDBQ/PC有机光导材料分散体系,制备的单层正电性有机光导器件具有优异的光导性能,V0=656.72 V,E1/2=0.16 μJ/cm2,Rd=29.10 V/s,Vr=71.47 V.
