TY - CONF A1 - Konnertz, Nora A1 - Böhning, Martin T1 - QCM System for the Characterization of Gas Sorption and Physical Aging of Membrane Polymers for Gas Separation Applications N2 - Polymers are favorable materials for gas separation membranes. In general, gas transport experiments are performed with films in the range of 100 µm thickness. However, in large-scale processes very thin selective polymer layers in the range of 100 nm to 1 µm are used. Moreover, it was shown that thin films behave different compared to thick films with respect to gas transport properties and physical aging as well. Thus, for fundamental research it is important to realize gas transport experiments with thin films. The Quartz Crystal Microbalance (QCM) is a very sensitive method to detect mass changes in the range of nanograms. Therefore, this method enables sorption experiments with thin films or layers attached to the QCM crystal (100 nm up to 1 µm). Here, we present the experimental set-up for using the QCM technique for characterizing the gas sorption behavior of thin polymer films in a temperature controlled pressurized environment (up to 50 bar) - also quartz crystals and crystal holders were optimized. The study aims for the characterization of long-term behavior and physical aging of high-performance polymers for gas separation membranes - such as polyimides and polymers of intrinsic microporosity (PIMs) and respective nanocomposites. Especially the differences of the behavior of thin films compared to films with thicknesses up to 100 µm as well as nanofiller induced-effects are adressed.
