Effect chemically induced surface barrier on xerographic properties

Abstract

In organic photoconductors, an anodic oxide layer acts as a barrier that prevents charge leakage to the substrate. A great challenge is forming a barrier for enhancing the xerographic properties of organic photoconductors. Here we report on a method for forming the surface barrier, which is simply comprised of dipping in extremely dilute alkaline solution and flattening in boiling water. The barrier demonstrates great enhancements in wettability and xerographic properties of dark decay, sensitivity and residual voltage of organic photoconductor.
