A process of treating metal oxide nanoparticles that includes mixing metal oxide nanoparticles, a solvent, and a surface treatment agent that is preferably a silane or siloxane is described. The treated metal oxide nanoparticles are rendered hydrophobic by the surface treatment agent being surface attached thereto, and are preferably dispersed in a hydrophobic aromatic polymer binder of a charge transport layer of a photoreceptor, whereby π-π interactions can be formed between the organic moieties on the surface of the nanoparticles and the aromatic components of the binder polymer to achieve a stable dispersion of the nanoparticles in the polymer that is substantially free of large sized agglomerations.
描述了一种处理金属氧化物纳米颗粒的工艺,包括混合金属氧化物纳米颗粒、溶剂和表面处理剂(最好是硅烷或硅氧烷)。经过处理的金属氧化物纳米颗粒通过表面处理剂的表面附着变得疏水,最好分散在光感受器电荷传输层的疏水芳香族聚合物粘合剂中,这样纳米颗粒表面的有机分子和粘合剂聚合物的芳香族成分之间可以形成π-π相互作用,实现纳米颗粒在聚合物中的稳定分散,基本上没有大尺寸团聚。
