3D Modeling of Gas Separation Membranes

The objective of this project is to predict a deformation of the developed gas separation membranes under different gas pressures. The gas separation membrane consists of the support layer (porous polyethylene film) and selective layer (polymerized ionic gel). Ionic gels are not self-standing materials, and the purpose of the support layer is to provide the mechanical strength and prevent rupture of the ionic gel under incoming gas pressure. The average pore size and the pore-size distribution of the support layer play an important role for the overall performance of the membrane. As the 3D geometry is generated from the membranes developed experimentally, simulations allow the researchers to study the deformation at the microscopic level and get more insights about the upper limit of the average pore size as well as the coefficient of variation in the pore-size distribution.
