“…Morales et al [230] prepared PANi by plasma poly merization of aniline in the presence of iodine vapor, using a radio frequency (rf) glow discharge at 13.5 MHz and an average power of 18 W. The polymerization was run at 92°C for different times (60-240 min) and in vacuo (1.5 × 10 3 mBar). Such I 2 PANi complex in form of thin film underwent morphological changes during heatingcool ing cycles (152 to 22°C).…”

A unique feature of molecular iodine by far, is its ability to bind to polymeric materials. A plethora of natural and synthetic polymers develop complexes when treated with molecular iodine, or with a mixture of mole cular iodine and potassium iodide. Many unexpected findings have been encountered upon complexation of iodine and the polymer skeleton, including the color formation, the polymer morphology changes, the compl exation sites or regions, the biological activity, and the electrical conductivity enhancement of the complexes, with poly iodides (I n¯) , mainly I 3¯ and I 5¯, as the actual binding species. Natural polymers that afford such complexes with iodine species are starch (amylose and amylopectin), chitosan, glycogen, silk, wool, albumin, cellulose, xylan, and natural rubber; iodinestarch being the oldest iodinenatural polymer complex. By contrast, numerous synthetic polymers are prone to make com plexes, including poly(vinyl alcohol) (PVA), poly(vinyl pyrrolidone) (PVP), nylons, poly(Schiff base)s, poly aniline, unsaturated polyhydrocarbons (carbon nano tubes, fullerenes C 60 /C 70 , polyacetylene; iodinePVA being the oldest iodinesynthetic polymer complex.

“…Morales et al [230] also polymerized pyrrole (py) under the abovementioned plasma conditions, affording I 2 Ppy. Only with polymers prepared at 240 and 300 min, the σ = f(1/T) showed linear Arrhenius behavior, with E a ≈1.1 eV.…”

“…Plasma polymerization technique, therefore, offers itself as an efficient alternative film fabrication means by reactions of the monomer in the gas phase to yield polymer films without having to redissolve polymer to cast films. Polypyrrole have been reportedly prepared by plasma polymerization [12][13][14][15][16][17][18][19][20][21][22][23][24] using various plasma sources. Nevertheless, none has mentioned the synthesis of PPy films by AC plasma polymerization.…”

“…Among the electroconductive polymer films, PPy has relatively good mechanical and thermal properties. However, only iodine-doped PPy films have been successfully synthesized so far by the plasma polymerization process [1][2][3], yet the conductivity of the films are not sufficient. We have synthesized the high conducting PPy films by the plasma polymerization process followed by exsitu doping technique using 4-ethylbenzenesulfonic acid (EBSA) [4].…”
