Abstract: | SiOx barrier layers under uniaxial stress For the study of the impact of defined mechanical uniaxial load on the gas barrier effect of a PET (Polyethylenterephthalate) film coated with silicon oxide SiOx a measurement device was designed. The developed system is modular and can be combined to measure both water vapour and oxygen transmission rate. The gas permeation was measured after a given strain and after unloading the strain on relaxed films.The results show that strain above 1 % can be critical for the increase of gas permeation of coated films under constant stress and 4 % for relaxed film. |
