## Abstract Polypyrrole (PPy) is a promising conductive polymer for tissue engineering and bioelectrical applications. However, its electrical conductivity deteriorates easily in aqueous conditions. Cell adhesion to PPy is also relatively poor. The goal of this study was to simultaneously improve t

Conducting polymer composites of polyethylene and polypyrrole (PE/ PPy), polypropylene and polypyrrole (PP/PPy) and poly(methyl methacrylate) and polypyrrole (PPMA/PPy) were prepared by means of a chemical modiΓcation method resulting in a network-like structure of polypyrrole embedded in the insula
## Abstract Anomalies in the temperature dependence of the conductivity of BF~4~^β^ doped polypyrrole were observed in cyclic measurements at temperatures between 250 K and 310 K. The anomalies were accompanied by endothermic effects in differential scanning calorimetry and are interpreted as being
