Biopolymer-based composition with adding of conductive polymer poly-(3,4-ethylenedioxythiophene) polystyrenesulfonate (PEDOT PSS) was made by mixing iota-carrageenan (CRG), polyvinyl alcohol (PVA) and PEDOT PSS followed freezing/thawing cycles. The method is environmentally friendly based on the formation matrix upon CRG, PVA porous physical gel due to It necessary mention that all components are well-known as biocompatible materials. resulting material stable in water also has swelling capability both distilled physiological solutions. Structure characterized means X-ray diffraction, optical electron microscopy. Electrophysical investigations were performed. conductivity immersed comparable dry value close 0.01 [S/cm].
