I have developed specialized expertise in pressure-volume-temperature (PVT) rheological testing for evaluating the thermodynamic properties of polymers. Over the past four years, I have extensively worked with the GÖTTFERT RG20 rheometer to conduct advanced PVT analyses across a wide range of polymer materials under varying conditions.
My work involves generating accurate PVT isobars and isotherms to simulate real-time polymer behavior and overcome experimental challenges in high-pressure environments. Using these data sets, I extract critical thermodynamic properties—including isothermal entropy change, adiabatic temperature change, and other relevant parameters—that are vital for assessing the potential of polymers as solid-state refrigerants. This capability supports advanced material selection and system design in next-generation refrigeration technologies.
The figure above illustrates the PVT apparatus I have utilized extensively for evaluating the thermodynamic properties of polymer materials considered for barocaloric solid-state refrigeration. This system enables precise measurement of pressure-volume-temperature relationships, allowing for the extraction of key thermodynamic parameters essential for assessing material performance under varying thermal and pressure conditions.
