METHOD FOR MANUFACTURING PHOTORECEPTOR LAYERS

摘要

The present teachings describe a process of forming a charge transport layer (CTL) coating dispersion. The process includes mixing a surfactant and a first organic solvent until the surfactant is completely solubilized. Fluoroplastic particles are added to the solubilized surfactant and first organic solvent while mixing to form a slurry. The slurry includes a particulate solid content of from about 5 weight percent to about 60 weight percent. The process includes mixing a base solution that includes a charge transport material, a binder, an antioxidant and a second organic solvent. The base solution is added to the slurry while mixing to form a CTL pre-mix dispersion.

1. A process of forming a charge transport layer coating dispersion, the process comprising:
mixing a surfactant and a first organic solvent until the surfactant is completely solubilized; adding fluoroplastic particles to the surfactant and first organic solvent while mixing to form a slurry wherein the slurry comprises a particulate solid content of from about 5 weight percent to about 60 weight percent of the slurry, wherein a coverage of the surfactant on the fluoroplastic particles ranges from about 45 percent to about 100 percent of a maximum adsorption; mixing a base solution comprising a charge transport material, a binder, an antioxidant and a second organic solvent; and adding the base solution to the slurry while mixing to form a charge transport layer pre-mix dispersion.
