Additional recommended knowledge
In one study nanofibers are produced from vanadium pentoxide nanofibers by a nanofiber seeding method. In this procedure EDOT is dissolved in an aqueous solution of camphorsulfonic acid (CSA) and a vanadium pentoxide nanofiber sol-gel and radical cationic polymerization is initiated by addition of ammonium persulfate. The resulting polymer precipitates from solution and has a general composition (PEDOT)(CSA)0.11-(HSO4)0.12(Cl)0.11(H2O)0.19. Washing with dilute hydrochloric acid removes the vanadium compound. The presence of the vanadium pentoxide seeds make the difference between the formation of PEDOT nanofibers (100 to 180 nanometer diameter and one to several micrometres long) and the formation of a more conventional granular morphology. When applied to a solid substrate such as PET, PEDOT non-woven films have slightly less optically transparency and about half the conductance of commercial PEDOT:PSS / PET films.PEDOT
