Preparation, Characterization And Electromagnetic Properties Of Polyaniline/Polypyrrole-Spinel Ferrite Nanocomposites

Organic-inorganic nanocomposites have received great research attention across the fields of polymeric chemistry, physical chemistry, organic chemistry and materials chemistry, because they combine the merits of the inorganic materials and the organic polymers, exhibiting the good mechanical, optical, electrical, magnetic properties. Polyaniline (PANI)/polypyrrole (PPY) have been extensively studied due to their adjustable conductivity, good environment stability and relatively easy preparation. Conducting polymer nanocomposites have become active in the field of organic-inorganic nanocomposites. In recent years, the synthesis of conducting polymer with magnetic behavior and magnetic nanoparticles containing conducting polymer have attracted significant attention.In this article, the conducting and magnetic PANI-LiNiLa ferrite nanocomposites with different PANI content were synthesized by in-situ aqueous polymerization using hydrochloric acid as dopant, ammonium peroxydisulfate as oxidant. We also prepared the conducting and magnetic PANI/PPY-ZnCuCrLa ferrite nanocomposites with different PANI/PPY content, using hydrochloric acid as dopant, ammonium...
