Synthesis and Characterization of Polyaniline Coated Carbon Black Composites

Abstract

Conducting polymer composites are examined universally for their use in various
applications such as corrosion protection, electromagnetic interference shielding, and Solar
cells and corrosion organic light emitting diode. In this coarse, here in, we made a strategy
for homogeneous coating of polyaniline on carbon black for their potential use in different
areas. Polyaniline coated carbon black shows larger surface area, high thermal stability,
electrical conductivity and better corrosion resistance. Major application of Carbon black is
as reinforcement in automobile tyres where it helps to conduct heat away from the treat and
belt area of the tyre, reducing thermal damage and increasing its life. β–
Naphthalenesulphonic acid (β–NSA) was used as surfactant and dopant which offers the
homogeneous coating on carbon black. Polyaniline (PANI)–carbon black composites were
prepared by chemical oxidative polymerization . The SEM of PANI– carbon black also
revealed the nano porous nature of coating, which can be used for selective incorporation of
other carbon forms. Morphology of PANI– carbon black displays the incorporation of carbon black in PANI matrix. Such prepared conformally polymer coated carbon black could be a
auspicious candidate for next generation building block material in several applications.
