Abstract

We present the fabrication and characterization of Au-polyaniline (Au-PANI) composite film using electrochemical synthesis.1 The PANI film is prepared by the chronopotentiometery technique on a platinum substrate. The as deposited PANI film was modified with Au particles using cyclic voltammetery. X-ray diffraction (XRD), Fourier transform infrared (FTIR), Raman spectroscopy and Scanning electron microscopy (SEM) techniques were used to establish the structural-morphological properties of the Au–PANI composite. XRD spectra revealed (100) and (200) planes in the composite.2 FTIR spectra displayed the main vibrational bands; including the characteristic peaks.3-4 SEM image of PANI shows rough and porous morphology, whereas Au-PANI composite exhibit mesh type structure with uniform dispersion of the Au-particles. It is observed that the Au-PANI composite showed enhanced Raman characteristics (due to SERS effect of Au particles) in comparison to the pure PANI film. The analysis revealed that the Au-PANI composite can be used for highly sensitive and selective chemical and biological sensing applications. References (1) Ali, Y., Kumar, V., Sonkawade, R.
