| Abstract | In the present work the nanocomposite containing polypyrrole and polystyrene were synthesized by solution cast technique. The effect of different (especially small) concentrations of polypyrrole on structural and optical properties was studied. The results revels that properties can be tuned significantly even with inclusion of small filler concentration in polymer matrix. Drastic decrease in the transmittance (up to 35%) has been observed even with small amount of filler concentration (i.e. 3%). INTRODUCTION Conducting polymers have attracted much attention due to their wide range of potential applications [1-5]. Researchers demonstrated that not all the polymers have insulating behavior. There are the conjugated polymers which in the neutral state show insulating or semiconducting characteristics and find the applications in the various field like solar cells sensors, organic light emitting diodes and optoelectronic devices [6-8]. Polypyrrole (PPy) is found to be most studied polymer because of its easily oxidizable nature, water solubility, commercial availability, high conductivity, best environmental stability and redox properties [9]. Polystyrene (PS) is found to be more suitable in terms of optical properties like color, high refractive index, chemically inert. It serve as resistant to oxidizing and reducing agents. Therefore blending PS with PPy opens new area of application e.g., as electromagnetic shielding and chemical sensing properties [10-13]. In the present study PPy-PS composites were prepared by solution casting method .The films were characterized for structural and optical studies. EXPERIMENTAL The Polypyrrole was prepared by chemical polymerization method. In the synthesis of Polypyrrole (PPy) FeCl3 is used as an oxidant and ethanol as solvent. Desired amount of pyrrole is added in ethanol and stirred continuously. In the prepared solution Fecl3 added drop wise. After 24 hours suspension it is filtered and washed with distilled water and acetone. The precipitate was dried about 1 hour at 60-700c. Prepared Polypyrrole (PPy) is doped in a doping percentage of 1 and 3 wt% in polystyrene (PS). Prepared solution was ultrasonicated and after constant stirring it was casted on Petri dish over the mercury and left to dry at room temperature. |
