    Abstract

    Organic disulfide compounds are having higher theoretical capacity than the conventional cathodematerial and are considered as the important storage material. Here, we are reporting the preparation of poly(2,2'-dithiodianiline) PDDA/multiwall carbon nanotubes, (MWCNTs) composites under different experimentalof composites. Composites were prepared in the presence of cetyl trimethyl bromide (CTAB), a cationicsurfactant, and also in the absence of CTAB. A physical mixture of PDTDA and MWCNTs was formed withunfunctionalized MWCNTs. Grafting of PDDA onto MWCNTs was performed by chemical oxidative polymerizationof 2, 2-dithiodianiline in the presence of amine functionalized MWCNTs. The composites of MWCNTs andPDTDA were characterized for structure, morphology anspectroscopy, Fourier transform Raman spectroscopy, scanning electron microscopy and UV-visible spectroscopy.The composite materials prepared by this method are expected to find applications as electrode materials forlithium batteries.
