An in-situ chemical polymerization method maintaining a low temperature in the range of 0-5 °C was used to synthesize nanocomposites with different weight percentages of cobalt aluminum oxide (CAO) in polypyrrole (PPy). Structural, morphological, elemental, and particle size characterizations were d...
