Electronic and Ionic Transport in Processable Conducting Polymers
Abstract
Stability studies of the electrical conductivity of poly(pyrrole tosylate) (PPTOS); poly(pyrrole dodecylbenzenesulfonate) (PPDBS) and polypyrrole/poly(styrene sulfonate) (PP/PSS) films and their laminated composites with epoxy/glass have been carried out at 160 F and 95% relative humidity. GPC molecular weight studies of poly(3-alkylthiophenes) has shown that the use of a multiangle laser light scattering (MALLS) detector, which provides absolute molecular weights, gives much higher values (2-5 times) than using polystyrene standards and an RI or UV-VIS detector. Thus, polystyrene is a poor molecular weight standard for these rigid rod poly(3-alkylthiophenes). Ion binding studies have been extended to polypyrrole/poly(styrene sulfonate) using Ru(bpy)3(2+)(bpy=2,2'-bipyridyl) and Ru(NH3)6(3+) as redox probes. Copolymers of pyrrole and 3-(1-pyrrolyl)propanesulfonate have also been studied this way. Partition coefficients were determined with a combination of UV-VIS spectrophotometric and voltammetric data.
