Device Simplifies Measurement of Gas Permeation in Films
DRESDEN, Germany, March 10, 2023 — Researchers at the Fraunhofer Institute for Material and Beam Technology IWS (Fraunhofer IWS) have developed a measuring technique for reliably determining the permeation rate of films. The method, which the researchers developed as part of the SimPerm project, looks at water vapor and oxygen permeation rates simultaneously — reportedly for the first time, the researchers said. The technology enables manufacturers, users, and developers of barrier films to determine the
