Description |
Freestanding polyparaphenylene films were obtained on polymerization of benzene at potential of 1.2V versus Al wire on substrates like
platinum/transparent conducting glass as an anode. The electrolyte used was chloroaluminate room-temperature melt, which was prepared
by intimate mixing of a 1:2 ratio of cetyl pyridinium chloride and anhydrous aluminum chloride to yield a viscous liquid. This liquid was
miscible in all proportions with benzene and other aromatic hydrocarbons in all proportions at room temperature. The polyparaphenylene films
deposited on platinum anode exhibited a prominent cyclic voltammetric peak at 0.7V versus Al wire as reference electrode in chloroaluminate
medium. The impedance spectra gave low charge transfer resistance. The diffused reflectance electronic spectra of the film gave the peaks at
386 nm and 886 nm. The PPP films showed electronic conductivity around 3–4×104 S/cm by four probe method under nitrogen atmosphere.
The polymer was also characterized by IR spectra, thermal studies, and SEM studies.
