Recent Advances in Photoconductive and Photosensitive Polymers

Abstract The synthesis and evaluation of photoconductive and photosensitive polymers have received considerable attention during recent years because of the increasing demand for such materials in electrophotography and related processes. By now, a wide variety of polymers, unmodified as well as modified chemically or otherwise, has been explored with regard to their potentialities in this field. An authoritative review by Stolka and Pai discussed the basic concepts in photoconductivity, summarizing the experimental techniques commonly employed in this context along with a review of original and patent literature on these systems available through 1976. In a contemporary article, Pen-well, Ganguly, and Smith reviewed the literature on N-vinyl -carbazole polymer systems with specific regard to synthesis, physicochemical property evaluation vis-a-vis their theoretical implications, and related topics. More recently, Biswas and Das reviewed the developments in carbazole-based polymer systems throusrh 1979.
