Abstract
Highly drawn poly(3-alkylthiophene) gels have been prepared by either drawing poly(3-alkylthiophene) gels or irradiating highly drawn soluble poly(3-alkylthiophene) with γ-rays. Both types of gels demonstrated reversible changes in length in the direction perpendicular to the drawing direction upon change in temperature, solvent composition and also doping. However, the change in length parallel to the drawing was negligible.
