Dynamic Measurement of Mass Transfer in Dry Cast Process of Polymer Solution Using Gravimetric and FTIR-ATR Techniques

The diffusion of small molecules as solvent through polymer materials is an important phenomenon in many different areas of science and engineering such as filtration and membrane production. The mass transfer during the solvent evaporation controls the membrane morphology and its properties. In thisstudy, the gravimetric [1] and FTIR-ATR technique [2,3] were used to measure concentration of polymer dynamically duringthe process of evaporating solvent
