Chemical Synthesis, Spectral Characterization and Electrical Conductivity Behavior of Poly(2-Methoxyaniline-Co-2-Chloroaniline) and its CuO Nanocomposite and Polypropylene Glycol Blend

Lakshmi Palaniappan, Jhancy Mary



Copolymerization of 2-chloro aniline and 2-methoxy aniline was achieved chemically by oxidative polymerization technique using ammonium persulphate as the oxidizing agent in acidic medium in the presence of sodium lauryl sulphate, an anionic surfactant. Copolymerization was also carried out in the absence of the surfactant to study the effect of surfactant on the thermal stability and electrical conductivity. The copolymer composite with CuO nano particles and blend with poly propylene glycol (PPG) has been reported for the first time. The materials synthesized are soluble in common organic solvents such as CCl4, DMSO, alcohol and DMF. The characterization has been carried out using FTIR spectroscopy, UV-Visible spectroscopy, 1H NMR, XRD and TEM. The presence of sodium lauryl sulphate reduces the thermal stability of the copolymer as shown by TGA/DTA analysis. The composite and blend are thermally more stable than the copolymer. The electrical conductivity measured is in the semiconducting range and of the order of 10-5 Scm-1. The change in conductivity due to the addition of SDS during the copolymerization is only marginal. The TEM image suggests that the copolymer CuO nanocomposite has been formed in which the CuO particles are embedded in the copolymer matrix.
