In situ absorption-reflection study of polypyrrole composites—switching stability

Size Control of Polypyrrole Particles

“…There are numerous reports on the electrochemical generation of PPy in the presence of PSS, and the exploration of the properties and applications of PPy/PSS composites, − but there is only one report describing the chemical synthesis of PPy in the presence of PSS …”

“…42 Also, since cations normally move faster than anions, the charge transport rate in the PPy/PSS composite will be faster. 43 There are numerous reports on the electrochemical generation of PPy in the presence of PSS, and the exploration of the properties and applications of PPy/ PSS composites, [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59] but there is only one report describing the chemical synthesis of PPy in the presence of PSS. 36 Our current interest in PPy/PSS is as a catalyst support in proton-exchange membrane fuel cells.…”

Biomimetic Conducting Polymers: Synthesis, Materials, Properties, Functions, and Devices

“…The parallel polymer degradation during polymerization is corroborated by the shift of specific stored charge (Q ox /w) with the polymerization conditions ( Table 2). 34,35 The degradation kinetics of a film can be followed through the specific stored charge: after polarization of the film at the overoxidation potential for a constant time the electroactivity of the film is checked by voltammetric control. 36 By repeating the procedure for different conditions (polarization time, potential, electrolyte concentration or temperature) the degradation empirical kinetics was obtained.…”

Synthesis, Characterization and Conductance Properties of Cobalt Chloride Doped Polyvinyl Alcohol / Polythiophene (PVA-Co-Pth) Nanocomposite Films

“…But, to resolve their solubility constraints and electrochemical properties of the conducting PANI composites are mostly owing to the polymerization methods, non-homogeneous composite formation, as well as doping dedoping properties of the conducting polymers, further more to increased process ability as well as mechanical properties, there is required to produce a real composite of conducting polymers with fundamental properties of the conductive polymers. The enhancement of these properties could be obtained through the forming of pyrrole copolymers or the forming composites PPY or through mixing with commercially available inorganic materials or polymers that provide better optically as well as mechanical characteristics, stability, and processing capacity [9,10] thus polypyrrole blends with an isolating polymer has good mechanical characteristics [11,12]. Electrochemical or chemical polymerization may be used to create polymer composites.…”
