Polymeric Nanofibriller Matrix on ITO Substrate for Flexible Chemical Sensing Applications

Abstract The authors present here a facile electrochemical approach to synthesize Poly(Aniline) nanofibriller matrix on ITO coated PET substrate for development of wearable or embeddable sensors. Electrochemical parameters were optimized even diametric synthesis and controlled length Poly (Aniline)) nanofibers. A three – step chrono potentiometric deposition was found be efficient the matrix. Precise tuning galvanic conditions during process highly effective repetitive towards controlling nucleation (Aniline) seeds that serves as basis nanofibers with presumable diameter range. Charge conduction behaviour studied via Linear Sweep Voltammetry semiconducting nature observed. synthesized nanofibrillar sensor platforms subjected Scanning Electron Microscopy (SEM), UV-VIS Spectroscopy FTIR spectroscopy elucidation morphological structural aspects. distribution network throughout uniform dendritic.
