By activating the polyethylene glycol (PEG-400) coated carbon of coconut shell, the homogenous shape and size of carbon was achieved. Then, γ- Fe2O3, TiO2, and carbon were mixed with PANi by an in situ polymerization method at low temperature 0-5 oC. Characterization process involved XRD, SEM, FTIR, VSM, and DC conductivity measurements. For radar absorber application, the functionalized polymer composites showed good electrical conductivity 0.45 S/cm to absorb the incoming electromagnetic energy. An efficient and effective reduction of Pb2+ ion from the water has been achieved by using this material. ## Keywords - Materials science - Coprecipitation - Composite material - Polymer - Polyaniline - Polyethylene glycol - In situ polymerization - Microstructure - Conductivity - Carbon fibers - Fourier transform infrared spectroscopy - Nanoparticle - Polyethylene - Polymerization - Characterization (materials science) - Chemical engineering - Composite number - Nanotechnology - Chemistry - Engineering - Physical chemistry --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
