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 △V_1s=50.16% and half decay time t_1/2=0.93 s.Its photoconductivities are much better than those of the photoreceptor using PMMA coating film.
