Abstract

In this research, at first, the tragacanth was carboxymethylated by monochloroacetic acid. Then the obtained carboxymethyl tragacanth (CMT) was reacted with a para-phenylene diamine to synthesize aminated CMT. The aminated CMT was grafted by polyaniline in various ratios by in-situ graft polymerization of aniline. The poly(aniline-co-melamine) copolymer was grafted on the aminated CMT by the in-situ graft copolymerization in various ratios consecutively. By the mentioned method, various conductive grated tragacanth were synthesized. After these steps, the conductive composites based on PANI and its copolymer with melamine grafted on tragacanth were prepared by the simple mixing method with PSMAC and MMT. The obtained grafted copolymers and their related nanocomposites were characterized by various techniques such as FT-IR, TGA, XRD, and SEM. The conductivity of the prepared samples was measured by two-probe chronoamperometry methods and the synthesized nanocomposites showed electrical conductivity. Furthermore, a solubility test was carried out for synthesized samples, and increases were observed in comparison to pure PANI.
