Poly(2-hydroxy-3-(methacryloyloxy) propane-1-sulfonate) (PHMPS), a polyhydroxyl sulfonate, was used
as both the template and the dopant in the in situ doping chemical oxidative polymerization of pyrrole.
The resultant PHMPS doped polypyrrole (PPy/PHMPS) nanoparticles were characterized with FTIR, UV–
vis, TGA, zeta potentials and TEM techniques. It was found that their size decreased and their dispersing
stabilities in water increased with the increasing of the feeding ratio of PHMPS. The PPy/PHMPS nanopar-
ticles possess high electrical conductivity at room temperature and the weak temperature dependence of
the conductivity. The conductivity–temperature heating curves are discussed.
