  • Publication number: 20150037732
    Abstract: 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.
