Description

The polyaniline-nanocarbon (PANI-NC) composite was synthesized by in situ polymerization of the aniline monomer (PBC-A&B) with reduced carbon from bituminous coal (RBC). The X-ray analysis confirmed the formation of the polyaniline-graphene oxide composite. The XRD result shows that the stacking height of the PBC-A increased due to the attachment of nitrogen group to the carbon lattice. The result of CHNS confirmed the increase in composition of nitrogen in PBC-A due to the treatment of RBC with aniline to form the polymer-nanocarbon composite. Optical analysis by UV absorption spectra revealed that the band gap is in the range of 3.29-4.27 eV. The AC conductivity, dielectric permittivity, and dielectric loss of the composite are measured within a frequency response of 10 Hz to 1 MHz. It is observed that one can tailor the band gap of the PANI-GO composite by varying the concentration of reduced carbon from coal. 2019 Elsevier Ltd. All rights reserved.
