Claims20
A carrier comprised of a core with a coating thereover comprised of at least one polymer resin and at least one fibrous carbon additive, wherein the outer surface of the coated carrier is fibrillated, and wherein the fibrillated outer surface of the coated carrier has a fiber surface area of about 10 fibers per 100 square microns to about 90,000 fibers per 100 square microns.
A process for preparing a coated carrier composition comprising:
- coating carrier core particles with a mixture of at least one solvent soluble polymer resin, insoluble fibrillated or non-fibrillated carbon fibers, an optional plasticizer compound, and a solvent or solvent mixture;
- and
- evaporating the solvent, wherein the resulting outer surface of the resin coated carrier is fibrillated, and wherein the fibrillated outer surface of the coated carrier has a fiber surface area of about 10 fibers per 100 square microns to about 90,000 fibers per 100 square microns.
