Surface Modification Of Polyanniline Nanofiber Using Silver nanoparticles To Enhance Sensing Properties

Yasir Ali, Vijay Kumar, A. S. Dhaliwal and R G Sonkawade

Volume 4, Issue 5, Page 368-372, Year 2013, Current Issue | DOI: 10.5185/amlett.2012.9422

Keywords: Polyanniline nano fibre; silver-nitrate; cyclic-voltametry; SEM, Raman.

Abstract: 

The surface of polyaniline nanofibres is modified by silver nano particles using cyclic voltametry (CV). The surface modifications induced by silver particles are confirmed by scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDX) and Raman spectroscopic techniques. The SEM micrographs show uniform distribution of silver particles on the surface of PANI nano fibers. Presence of silver particles was confirmed by EDX. Structural variations induced after reduction of Ag-metal particles and formation of polaron and bipolarons are studied by Raman spectroscopy. Copyright © 2013 VBRI press.
