摘要: 制备了聚甲基丙烯酸甲酯(PMMA)LB复合膜,将其作为阻挡层首次应用于机能分离型光电导体领域。从π-A曲线发现PMMA单分子膜具有表面压力的各向异性和松弛特性。TEM照片显示,PMMA分子链在复合膜中有序排列。转移比、UV和XPS研究表明,复合膜沉积均匀。以PMMA-LB复合膜作为阻挡层的光电导体表面充电电位V0=1518V,光照1s后的光衰百分率△V1a=50.16%,半衰期t1/2=0.93s.

Abstract: In this paper, poly(methylmethacrylate)(PMMA) Langmuir-Blodgett(LB) multilayer films were prepared and applied to the field of a separation functional photoreceptor as a resistant interface layer for the first time.From the π-Acurves.it was found that the PMMA monolayer has anisotropism and relaxation of surface pressure.TEMphotograph showed the orientation and arrangement of PMMA chains in the multilayers.Investigations of transfer ratios, UVand XPSindicated that the deposition of multilayers is uniform.The photoreceptor using PMMA-LBmultilayer films as a resistant interface layer, CuTsPc-LBfilms as a charge generation layer, PVK as a charge transportation layer exhibited surface potential V0=1518 V, percentage of potential discharge after one second exposure △V1s=50.16% and half decay time t1/2=0.93 s.Its photoconductivities are much better than those of the photoreceptor using PMMA coating film.
