Express Measurement of the Permeability of Solvents Through Nanoporous Membrane Materials and Barrier Films by Detection of Dynamic Pressure Reductions

A method and experimental setup for measuring the permeability of membrane and film materials has been developed. This method is based on determining the kinetics of the pressure change in a liquid above a membrane. The permeability of solvents through a glassy polymer is studied over wide ranges of...

Description
Summary:A method and experimental setup for measuring the permeability of membrane and film materials has been developed. This method is based on determining the kinetics of the pressure change in a liquid above a membrane. The permeability of solvents through a glassy polymer is studied over wide ranges of temperature and pressure. This method and the associated apparatus can be used to determine the permeability of solvents through membrane materials with high accuracy for both convective and diffusive liquid transport.
