Gum ghatti-polymethacrylic acid-polyaniline based electrically conductive hydrogel with an interpenetrated network (IPN) structure was prepared through a two step aqueous polymerization. In the first step, cross linked network of polymethacrylic acid onto Gum ghatti was prepared using N,N′-methylene-bis-acrylamide (MBA) and ammonium persulfate (APS) as a cross linker-initiator system under microwave irradiation. Optimum reaction conditions affording maximum percentage swelling were: solvent (ml) = 10, MAA (mol L⁻¹) = 0.236 × 10⁻³, APS (mol L⁻¹) = 0.175 × 10⁻¹, MBA (mol L⁻¹) = 0.32 × 10⁻¹, reaction time (s) = 85, microwave power (%) = 100 and pH 7.0. The semi-interpenetrating networks was converted into a IPN through the impregnation of poly(aniline) chains and resulting IPN was doped with HCl. The maximum conductivity (2.69 × 10⁻⁴ S cm⁻¹) was observed with 2.0 N HCl and 0.658 × 10⁻³ …
