Tubular Polypyrrole Synthesied by in Situ Doping Polymerization in the Presence of Organic Function Acids as Dopants

摘要

Tubular polypyrrole(PPy) could be synthesized by in situ doping polymerization in the presence of #beta#-naphthalene sulfonic acid (NSA) as dopant. The resultant tubular PPy-NSA not only exhibits high room temperature conductivity (#sigma#_(RT)=10 S/cm) but is also soluble in m-cresol. The molecular structure of PPy-NSA is identical to the characteristic structure of PPy synthesized by a conventional method. It has been demonstrated that NSA dopant with large molecular size and plate-lebe structure is a key factor to control formation of tubular PPy-NSA.
