Improvement of Physical Properties of Polypyrrole by Tin Dioxide Nanoparticles

Polypyrrole (PPy) is a conductive polymer with a conjugatedelectron backbone that displays unusual electronic properties and uses in batteries, supercapacitors, electrochemical (bio)sensors, conductive textiles and fabrics, mechanical actuators, electromagnetic interference shielding, antistatic coating, anddrug delivery systems [1, 2]. However, the principal problems with the practical utilization of conducting polymers like PPyinclude its poor mechanical properties like brittleness and lowprocessibility. Nanocomposites are a special class of materials having unique physical properties and wide applicationpotential in diverse areas. Novel properties of nanocomposites can be obtained by the successful combination of the characteristics of parent constituents into a single material. Encapsulation of inorganic nanoparticles inside the shell of conducting polymers is the most popular and interesting aspect of nanocomposites synthesis. These materials differ from both the pure polymers and the inorganic nanoparticles in some of the physical and chemical properties [3, 4].
