Nanocomposite of Polyaniline and Na+-Montmorillonite Clay

摘要: Nanocomposites of conducting polyaniline (PAN) with inorganic Na+−montmorillonite (MMT) clay were synthesized by the emulsion polymerization method. The dodecylbenzenesulfonic acid (DBSA) was used for both dopant and emulsifier. Analyses X-ray diffraction patterns demonstrated that PAN-DBSA intercalated between layers at nanoscale level (<10 A). We observed induced more disordered state in PAN-DBSA/clay nanocomposites. From temperature-dependent dc conductivity [σdc(T)] experiments, we investigated charge transport mechanism systems. interaction FT-IR spectra. results differential scanning calorimetry (DSC) thermogravimetric analysis (TGA) showed improved thermal stability nanocomposite materials. σdc these systems 101−10-2 S/cm room temperature, varying molar ratio. σdc(T) nanocomposite...
