Electroviscoelastic effect of doped poly(3-hexyithiophene)

摘要

Poly(3-alkylthiophene) is the first soluble conduct-ing polymer consisting of a thiophene backbone and flexible alkyl groups as side chains [1,2]. The side-chain substitution allows insoluble polythio-phene to be soluble in organic solvents, and also fusible [3]. The good processability has opened a new door to advance the science and technology of conducting polymers [4-7], Here we report on the dynamic viscoelasticity of doped poly(3-alkylthio-phene) in an electric field.
