An innovative method for preparation of nanometal hydroxide superabsorbent hydrogel

► A novel preparation of conducting nanometal hydroxide hydrogel is undertaken. ► A superabsorbent hydrogel was prepared through polymerization of acrylic acid/acrylate. ► Electro-deposition of nanometal hydroxides of copper and iron in hydrogel network has been developed. ► Swelling characteristics and kinetics in different media has been investigated. ► Conductivity measurements indicated an improvement in conductance of the resulting hydrogel.
