Polypyrrole/poly(ethylene-co-vinyl acetate) conducting composites with improved mechanical properties were prepared by a similar method [167], In addition, polyaniline/polystyrene [168] and polyaniline/poly(alkyl methacrylate) [169] composites have been synthesised. A solution of persulphate in aqueous HC1 was added to an o/w HIPE of polymer and aniline in an organic solvent, dispersed in aqueous SDS solution, causing aniline polymerisation. Films were processed by hot- or cold-pressing.

Materials studied are polyaniline, poly(3-octylthio-phene)(POT), and mixtures of poly(3-octylthiophene) (POT) and poly(ethylvinylacelate) (EVA). The synthesis of polyaniline was carried out by oxidation of aniline monomer using (NH4)2S20g in HCl (1 M) -I-HBF4 (1 M) or in the eutectic NH4F, 2.35 HF as... 

As the degradation of polyaniline occurs via an imine intermediate [281,284], Kim et al. [285] prepared self-doped polymer by alkylsulphonate substitution in the polymer backbone, Besides self-doping for a facile redox process, the perceived advantage of this bulky substituent includes the protection of nitrogen centres from nucleophiles responsible for irreversible degradation of polyaniline. Poly(aniline N-butylsulphonate) retained its reversible electrochromic response up to 150 000 cycles when scanned between its oxidized and reduced states (between 0.2 and 0.5 V) then started diminishing slowly. The excellent redox cyclability of poly(aniline N-butylsulphonate) over unsubstituted polyaniline was also confirmed by chronoabsorptom-etry by Kim et al. [285],...

Confocal Raman microprobe spectroscopy was used to characterise polyaniline/poly(V-vinyl carbazole), polypyrrole/poly(V-vinyl carbazole) and polypyrrole/ polyaniline films (or reverse order of each pair in the films). Two types of film were observed, depending on the conditions. Either the second polymer was incorporated into the initially coated layer or a doublelayer film with a well-defined interface was formed. Electrolysis of pyrrole and aniline monomer mixtures gave films rich in pyrrole when the pyrrole aniline molar ratios were greater than 0.12. However, polymerisation of V-vinyl carbazole and pyrrole monomer mixtures gave only polypyrrole over a wide range of molar ratios (121). 

Schottky devices have recently been fabricated by thermal evaporation of indium on polyaniline, poly(o-anisidine) and poly(aniline-co-or oanisidine), respectively [103]. The values of the rectification ratio, the ideality factor and the barrier height of an indium/poly(o-anisidine) have been experimentally determined as 300,4.41 and 0.4972, respectively. The observed deviation from the Schottky behaviour for these devices seen at higher voltages has been explained in terms of either the Poole-Frenkel effect or due to the presence of a large number of defects containing the trapped charges existing at the indium/poly (aniline-co-or oanisidine) interface.

Polyaniline was used as hole injection material for polymer hght-emitting devices (PLED) spin-coated from a water-based polyaniline/poly-styrenesulfonate (PAni/PSS) dispersion. Data presented here were based on red, yellow, green, and blue LEPs. Depending on the applied bias voltages, the devices were studied by electrical impedance spectroscopy (EIS) in a wide frequency range. Experimental data could...
