Description
Summary:In this work, the structural and gas sensing properties of polyaniline nanostructures deposited on 36° lithium tantalite (LiTaO3) conductometric transducers was investigated. The polyaniline nanostructures were synthesized via an electropolymerization method. The morphology of the nanostructured polyaniline was characterized using Scanning Electron Microscopy (SEM). It was observed that the electropolymerised film was a three-dimensional (3D) porous structure of polyaniline fibers and nanotips. The conductometric sensors were exposed to different concentrations of hydrogen (H2) gas at room temperature.
