Synthesis Characterization And Electrical Conductivity Of Poly 2- ChloroanilineMMT And Poly 2-ChloroanilineNa-Bentonite Nano Composites In The Presence Of Surfactants

Abstract The poly 2-chloroaniline Montmorillonite P2ClAnMMT and poly 2-chloroanilineNa-Bentonite P2ClAnNa-Bentonite nano composites were prepared by insitu chemical oxidative polymerization method using ammonium per sulphate oxidant HCl dopant sodium lauryl sulphate surfactant in the presence and absence of dodecyl benzene sulphonic acid DBSA. The crystallite size of the polymer composites as calculated by Debye-Scherrer equation from XRD data shows the particle size in the range 20-35 nm. The composites were stable upto 550o C. The impedance and the conductance as measured in the frequency range from 20 Hz to 1 MHz at room temperature showed an increase in conductivity in the composite when compared to pure polymer. Among the P2ClAnclay nano composites synthesized the poly 2-chloroanilineMontmorrilonite in the presence of dodecyl benzene sulphonic acid P2ClAn-DBSAMMT has the maximum conductivity of 3.6 x 10-3 Scm at room temperature. The crystallinity and orientation is retained in the P2ClAn-DBSAMMT and hence it has high conductivity than the other composites. The composites synthesized behave as organic metals due to their semiconducting nature.
