Conducting polymers5
  • Nanofiber Seeding is a process to control the bulk morphology of chemically synthesized conducting polymers. (wikipedia.org)
  • Bulk quantities of nanofibers of conducting polymers such as polyaniline, can be synthesized in one step without the need for conventional templates, surfactants, polymers, or organic solvents.3 Conventional oxidative polymerization approaches to nanostructured conducting polymers include the use of hard template zeolites, opals, and controlled pore-size membranes, or soft template such as polymers and surfactants. (wikipedia.org)
  • This method can be extended to all major classes of conducting polymers, including polypyrrole, PEDOT and other polythiophenes etc.23 Nanofiber seeding is a convenient approach to obtain thin, substrate-supported, transparent films of nanofibers of conducting polymers without requiring any bulk processing steps. (wikipedia.org)
