Conducting polyaniline-polymannuronate (PANI-PM) composites have been prepared by in situ deposition technique by placing different wt.% of fine grade powder of polymannuronate (5, 10, 15, and 25%) during polymerization of polyaniline. The oxidative polymerization of aniline was carried by using ammonium persulfate as oxidant. Further the temperature-dependent DC conductivity of PANI-PM composites was studied within the range of 300 ≤ T ≤ 500 K. The conductivity data shows an evidence for the transport properties of PANI-PM composites. This study in turn supports the strong interaction of PANI with PM in the composites. Based on the DC conducting properties the composites signify the future development of new materials for the creation of new bio-nanocomposites that has a multi-component and multifunctional material.
