Patent ID: 8465893

Claim:
A flexible electrophotographic imaging member comprising: a flexible electrically conductive substrate; at least one imaging layer positioned on a first side of the substrate; and an anticurl back coating positioned on a second side of the substrate opposite to the at least one imaging layer, wherein the anticurl back coating comprises carbon nanotubes dispersed in a polymer blend and further wherein the polymer blend comprises an anti-static polymer, a bisphenol polycarbonate, and low surface energy polycarbonate, the low surface energy polycarbonate being an A-B di-block copolymer comprising two segmental blocks, the first segment block (A) being wherein x polydimethyl siloxane (PDMS) repeat units is from about 10 to about 70 and y is from about 1 to about 15, and the second segment block (B) being selected from the group consisting of wherein z is from about 50 to about 400; wherein a relative weight ratio of the anti-static polymer:bisphenol polycarbonate:A-B diblock copolymer:carbon nanotubes is from 40:30:5:1 to 20:30:25:15.
