Physics of Polymer Mixtures at High-Pressure

Several physical properties of polymer/gas systems are measured in this lab. Recently we coupled a gravimetric technique with an optical technique to measure, concurrently, fully experimentally, solubility, diffusivity, interfacial tension and specific volume of polymer/gas mixtures up to 250°C and 13.5MPa. The technique has been reported on Polymer Testing journal in 2011.
