AB  - In the present work novel conductive organic-inorganic nanocomposites were 
      produced by grafting of pyrrole monomer onto silanized Laponite RD utilizing 
      emulsion graft polymerization. Influence of some important factors like 
      concentration of monomer, initiator and surfactant were investigated on grafting 
      efficiency. Grafting of polypyrrole chains onto modified Laponite RD was verified 
      by Fourier transform infrared spectroscopy (FT-IR). Scanning electron microscope 
      (SEM) revealed the spherical particles of nanocomposite with average diameter of 
      271.5 nm. XRD pattern showed that molecular framework of pure polypyrrole almost 
      remains same in nanocomposite. Surface area and pore volume of Laponite RD, 
      measured by Brunauer-Emmett-Teller (BET) analysis, was also altered indicating 
      effective grafting of polypyrrole chains onto modified substrate. Maximum 
      grafting efficiency (%), determined gravimetrically, was 87.3% at monomer, 
      initiator, and surfactant concentrations of 1.50, 1.00, and 0.50% respectively. 
      Prepared nanocomposites with grafting efficiency of 87.3% have displayed maximum 
      electrical conductivity of 0.23 x 10(-2) Scm(-1). These nanocomposites can be 
      used for manifold applications like biomedical and energy storage devices.
