摘要
Oxotitanium phthalocyanine (TiOPc) nanometer particles dispersed in polycarbonate (PC) resin are obtained successfully by the method of mechanical sand grinder. The mean grain sizes of TiOPc particles and the particle morphology are measured by particle size analyzer and TEM. The xerographic properties of TiOPc nanometer particles are investigated in function-separated single-layer photoreceptors that consist of TiOPc nanometer particles as the charge-generation material (CGM) and ac-naphthalic hydrazone (alpha-NH) as the charge-transportation material (CTM). It is found that the photosensitivity of the function-separated single-layer photoreceptor is higher than that of the double layer device (same CGM and CTM). The photoconductivity-particle size relationship study shows that the smaller the particle size of TiOPc, the better the photoconductivity, which may result from the large specific surface area of the TiOPc nanometer particles.
