Abstract

The influence of boric acid doping on ethanol vapor sensing performance of electrospun copper indium disulfide (CuInS₂) nanofibers in the presence of various levels of relative humidity was examined for the first time. Pure and boric doped CuInS₂ nanofibers are prepared through electrospinning method and characterized by X-ray diffraction, scanning electron microscope, Fourier transform infrared spectroscopy and Thermogravimetric analysis techniques. It was found that not only the ethanol sensing performance but also base line current of the CuInS₂ nanofiber based sensors are greatly influenced by the boric acid doping level. Maximum sensitivity was obtained with pure CuInS₂ under humid conditions. Kinetic studies indicated that ethanol vapor adsorption kinetics strongly depend on level of the relative humidity and the ethanol concentration.
