Two steps synthesis and conductivity of polyacrylamide/Cu conducting hydrogel
Source abstract
Abstract
Abstract Cu microparticles are dispersed in a polyacrylamide (PAM) superabsorbent by a two steps aqueous solution polymerization. Based on the electrical conductivity of Cu and the water absorbency of PAM, a novel conducting hydrogel (PAM/Cu) with a conductivity of 6.12 mS cm −1 and percolation threshold of 3 wt% is prepared. An appended network structure model for explaining the electrical conduction of PAM/Cu hydrogel is proposed. And the effects of crosslinker, initiator, monomer concentration, Cu content, reaction temperature, water absorbency on the electrical conductivity are also investigated according to the structure model.
