Ws. Yin et al., CONDUCTING COMPOSITE FILMS BASED ON POLYPYRROLE AND CROSS-LINKED POLY(METHYL ACRYLATE CO HYDROXYETHYL ACRYLATE), European Polymer Journal, 34(5-6), 1998, pp. 779-782
Polypyrrole/crosslinked poly(methyl acrylate-co-hydroxyethyl acrylate)
(PMA/HEA) conductive composite films were prepared by vapor phase pol
ymerization of pyrrole within the silicon crosslinked PMA/HEA network
using anhydrous ferric chloride as oxidant. It was found that the cond
uctivity decreases with an increase in the amount of tetraethyl orthos
ilicate (TEOS) crosslinker. With an increase in the amount of ferric c
hloride, the conductivity increases and then decreases in spite of the
increase in polypyrrole content in the conducting composite films, gi
ving a maximum conductivity of 2.5 S/cm at 0.6 g FeCl3. The conductivi
ty also strongly depends on other synthetic conditions such as the rea
ction time, the nature and the amount of the solvent in pyrrole soluti
