Polypyrrole 2,4-dimethyl

For biosensor applications, it is reported that a change in polypyrrole absorbance is induced when the material is exposed to dimethyl-methyl phoshopnate (DMMP) [32], as shown in Fig. 16, where 40% reduction occurred in the UV/Vis absorbance band. DMMP is a chemical precursor to the nerve agent sarin. It is reported that the DMMP interacts electronically with the polypyrrole to increase the amount of free... 

Poly(l-vinylimidazole)i2-[Os-(4,4 -dimethyl-2,2-bipyridyl)2Cl2] and poly(vi-nylpyridine)-[Os-(Ai,Ai -methylated-2,2 -biimidazole)3] were reported for their efficient capability of mediating electrons transfer between bacterial cells to electrodes. With S. oneidensis, the osmium redox polymer modified anode showed a 4-fold increase in current generation and a significant decrease in the start-up time for electrocatalysis. Using an anode modified with electropolymerized polypyrrole, a dramatie improvement in energy output was noticed in the MFCs. MFCs with a polypyrrole/ anthraquinone-2,6-disulfonic disodium salt (PPy/AQDS)-modified anode... 

Films prepared in a similar manner with Hydrin C are those utilizing poly(N,N -dimethyl-2,2 -bipyrrole) [220], and polypyrrole [221]. Electrochromic films of Hydrin C and poly(o-methoxyaniline) have also been produced in which the aniline polymer is chemically polymerized in the presence of p-toluene sulfonic acid and blended with Hydrin C with the blend cast from solution [219]. Another example in which an electrochromic polymer was electrochemically polymerized in the presence of an insulating polymer is that of polypyrrole-polyjether urethane) or polypyrrole-poly(ethylene-co-vinyl alcohol) composite films [222]. Both films switched between a yellow reduced state to a bluish brown oxidized state, similar to polypyrrole.

Poly(p-phenyleneterephthalamide) is soluble in dimethyl sulfoxide and is used to produce the well-known Aramid fibers. A blend of this material and polypyrrole in the form of film was prepared by the electrode coating method and using a / -toluenesulfonate salt as electrolyte [82]. A comparison of the mechanical properties of the blend with pure polypyrrole showed that the blend is a tougher material with a higher modulus and lower elongation at break. Treatment of the blend with HCl raises the conductivity but also increases hardness and toughness.
