Abstract
This research presents a novel thermo-responsive sol–gel (dopant) combination and evaluation of the actuating responses due to various heat treatment temperatures. In this project, samples of antimony-doped tin oxide (ATO) doped with 0.1% cobalt oxide (0.1% Co2O3) sol–gel on carbon/silicon substrates are used to model the implementation of sol–gel coatings into carbon fiber composite systems. While ATO is a well-known transparent conductive material, the addition of cobalt oxide (Co2O3) alters its morphology and optical parameters at low annealing temperatures. By altering the ATO (0.1% Co2O3) heat treatment temperatures, the grain size starts to increase at 200 °C. However, when approaching 500 °C, Raman spectroscopy shows that the increase in intensity of ATO (0.1% Co2O3) is lower than ATO undoped. Scanning electron microscopy is used for imaging, and energy dispersive spectroscopy will be used for the composition analysis. Optical reflectance is reported via Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy analysis.
