This project aims to understand the permeation of water through commercially relevant non-porous polymeric membranes. Permeation, solubility and diffusivity will be studied in the vicinity of the glass transition temperature to elucidate the changes in free volume that occur through this transition. Non-linear concentration gradients due to anisotropic swelling will be probed using novel laminated membrane systems. Water clustering will be evaluated by Fourier transform infrared spectroscopy and nuclear magnetic resonance. Results are proposed to be used to build a new phenomenological model of water permeation that can be used directly by engineers in the design of industrial membrane systems.

该项目旨在了解水通过商业相关的无孔聚合物膜的渗透。将在玻璃化转变温度附近研究渗透性、溶解度和扩散率，以阐明在此转变过程中发生的自由体积的变化。将使用新型层压膜系统来探测由于各向异性膨胀而产生的非线性浓度梯度。将通过傅里叶变换红外光谱和核磁共振来评估水的聚集。建议将结果用于建立新的水渗透现象学模型，工程师可以直接使用该模型来设计工业膜系统。
