  • Publication number: 20210095398
    Abstract: Embodiments of this invention are directed to substituted polyaniline nanofibers and methods of synthesizing and using the same. The invention is also directed to polyaniline derivatives that can be synthesized without the need for templates or functional dopants by using an initiator as part of a reaction mixture.
    Type: Application

  • Patent number: 8653231
    Abstract: The present invention involves synthesizing conducting polymer nanofibers by mixing an oxidant solution with a monomer solution, which includes a monomer and an oligomer of the monomer that is used as an initiator. The oxidant solution includes an oxidizing agent, or oxidant, such as ferric chloride to oxidize the monomer, the oligomer, or both, and begin polymerization. By including an initiator in the form of the oligomer, which may have a lower oxidation potential than the monomer, the rate of polymerization is accelerated, resulting in the nanofibrous morphology. Therefore, the conducting polymer nanofibers may be synthesized without the use of surfactants, hard templates, or seeds, resulting in a simplified and accelerated polymerization process, which enhances homogenous nucleation of the conducting polymer nanofibers.
