Abstract
This article aims to determine the thermal conductivity of an aerogel sample made from organic products, with and without the addition of graphene oxide GO. In addition to thermal conductivity, the article presents energy absorptivity in the form of thermal radiation, for both samples. The thermal conductivity of the samples was determined by the hot wire method with numerical treatment of least squares. To analyze the radiative absorptivity of the sample in the infrared range, a FTIR 100 IR-NIR spectrometer was used.
