The aim of the manuscript was to study the effect of CMGG nanoparticles concentrations on PANI/CMGG nanocomposites. Aniline has been polymerized in the presence of CMGG nanoparticles dispersed solution in acidic medium. Then nanocomposites have been characterized by FTIR, XRD, SEM and TEM. The size of the PANI/CMGG nanocomposites particles has been found in the range of ~90–280 nm. The results conclude that conductivity of the nanocomposites inversely depends on the concentration of the CMGG nanoparticles.
