Electrical properties of gamma-crosslinked hydrogels incorporating organic conducting polymers

摘要

Hydrogel composites containing nanoparticles of the protonated emeraldine form of polyaniline (PANI-PE) have been synthesised by gamma-irradiation,using either polyvinyl pyrrolidone (PVP) or polyvinyl alcohol (PVA) as steric stabilisers.Swelling behaviour of both hydrogels is reported,together with an electrical characterisation of composites,before and after gel network formation,performed by cyclic voltammetry and impedance spectroscopy.Similarities and differences between the two composite systems are discussed.
