Abstract

In this paper, the mechanical actuation of conducting polymer film when exposed to a specific analyte is analyzed. This measurement of actuation could be used as sensing apparatus. A conducting polymer-carbon black composite sensor shows good selectivity for toluene vapors. The interaction between the conducting polymer and toluene vapors is because of the solubility interactions. The solubility-based interaction would also result in a volumetric change of the polymer film which in turn would alter the conductivity of the sensor film. Here laser Doppler vibrometry, a non-contact method, is used to investigate the average displacement in a direction normal to film produced by the absorption of the vapors and hence detect the volumetric change. Therefore, this paper shows sensing action by conducting polymer composite can be detected by measuring the displacement produced during analyte vapor absorption.
