Core-shell structure polyaniline / silver conductive nano composite material and preparation method thereof

The invention relates to a core-shell structure polyaniline / silver conductive nano composite material and a preparation method thereof, and belongs to the technical field of conductive polymer composite materials. The preparation method comprises the following steps: firstly, reducing silver nitrate or silver ammonia solution in a reverse-phase microemulsion system to prepare monodisperse silver nanoparticles; secondly, adding aniline / acid-doped reverse micelle solution, taking silver nanoparticles as seeds, and carrying out the oxidative polymerization of the polyanilinee on the surfacesof the silver nanaoparticles aniline; and making the silver nanoparticles being dispersed in the polyaniline to form the core-shell structure polyaniline / silver conductive nano composite material. The core-shell structure polyaniline / silver conductive nano composite material has good electrical conductivity, thermodynamic stability and processability, can be potentially used for conductive components, electrode active
