Anisotropy of Electroactive Strain in Highly Stretched Polypyrrole Actuators
TL;DR: In this paper, an anisotropic electroactive strain response (e⊥/e∥ = 38) was observed due to the stretching of polypyrrole films to high elongations.

In situ observation of dynamic elastic modulus in polypyrrole actuators
TL;DR: In this article, the elastic modulus of polypyrrole in situ during actuation in a variety of electrolytes was probed and it was shown that the electroactive response in dilute 1-butyl-3-methylimidazolium hexafluorophosphate can be changed from cation-to anion-dominated by adjusting the applied potential waveform.

Anisotropic actuation of mechanically textured polypyrrole films
TL;DR: In this paper, free-standing polypyrrole films have been stretched or cold-rolled to produce uniaxially and biaxial textured films, which show an increase in conductivity up to 3× when compared to unprocessed films, due to polymer chain alignment.

- 01 Jan 2007
TL;DR: In this article, the authors used diffraction and electron microscopy to investigate the microstructure of polypyrrole and proposed a new description consisting of disordered polypolyrole chains held together by small crystalline bundles, around which solvent and counterions are randomly distributed.
