Abstract The investigation of clay based polymer nanocomposites has opened the door for the development of novel, ecofriendly advanced nano materials that can be safely recycled. Because of their nanometer size dispersion, these nanocomposites often have superior physical and mechanical properties. In this study, novel nanocomposites of poly( o ‐toluidine) (POT) and organically modified montmorillonite (MMT) were synthesized using camphor sulfonic acid (CSA), cetyl pyridinum chloride (CPCl), and N ‐cetyl‐ N , N , N ‐trimethyl ammonium bromide (CTAB) to study the role of surfactant modification on the intercalation. The in situ intercalative polymerization of POT within the organically modified MMT layers was analyzed by FTIR, UV–visible, XRD, SEM as well as TEM studies. The average particle size of the nanocomposites was found to be in the range 80–100 nm. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2007
