    摘要： A silicone overcoat (SOC) layer having a crosslinked polysiloxane composition comprising a perfluoropolyether segment are disclosed. The polysiloxane composition is the product of the hydrolysis and condensation of a SOC formulation comprising a perfluoropolyether compound, an aromatic silicon-containing compound, and a silicon-containing hole transport compound. An electrophotographic imaging member having such a SOC layer has improved properties.

    摘要： 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.

    摘要： Provided are a silane-phenol compound, a crosslinked siloxane-phenolic protective overcoat layer thereof, and an electrophotographic imaging member such as photoreceptor. The silane-phenol compound comprises (i) a phenol group and (ii) a silane group selected from the group consisting of alkoxysilyl, arylalkoxysilyl, aryloxysilyl, alkylaryloxysilyl, and combination thereof. The silicone overcoat is made from a formulation comprising the silane-phenol compound and a hydroxymethylated hole transport compound. The crosslinked siloxane-phenolic overcoat may be used to manufacture an electrophotographic imaging member such as photoreceptor with improved properties such as abrasive resistance, good image quality and cleanability, etc.
