Electrical and thermal properties of PANI–Mmt nanocomposites in strongly acidic aqueous media

Polymer nanocomposite have presented a growing importance in many uses such as the higher protection of steel from corrosion, lifelong thermal and electrical performance of their nanocomposite due to their morphological improvements with nanocharges hence become an alternative to pure polymers. The nanocomposites are mixed materials synthesized by polymeric matrix with small percentage of montmorillonites (Mmt) as inorganic reinforcement which can be recycled and not toxic. The dispersion of Mmt is facilitated by the organophilisation of their structure by alkylammonium. It is a question of following the evolution of the electrical conductivity and thermal stability of nanocomposite according to time for samples aged in strongly acidic solutions at various temperatures. Fractions of products will be taken regularly and characterized by FTIR–UV, RX and GPC. Conductivity will be followed by the four probe method. The study will be followed by the evaluation of morphology by microscopy and the thermal stability by DSC–TG.
