The value of specific heat capacity was measured with a PerkinElmer DSC 8000 differential scanning calorimeter using modulated temperature mode of operation. The heterogeneous material under investigation was the graphene oxide/rubber composite, which is used in the production of roller bearing seals. Two types of rubber have been used as the basic matrix of composites: the hydrogenated acrylonitrile butadiene rubber and the fluoroelastomer. Graphene oxide reduced with sodium hypophosphite was applied as a compo-site filler. The main goals of the work was to expand the database of thermophysical properties of materials and to inves-tigate the influence of material heterogeneity on the results of specific heat capacity measurements obtained with small-sized test samples.}, type={Article}, title={Investigations of the specific heat capacity of selected heterogeneous materials}, URL={http://www.journals.pan.pl/Content/131569/9_AOT-00667-2023_Wilk.pdf}, doi={10.24425/ather.2024.150855}, keywords={Specific heat capacity, Heterogeneous material, Rubber composite, Modulated temperature, StepScan mode}, }
