The barrier layer 14 contains nanoparticles of Li-type montmorillonite, and polyimide. The ratio of the maximum diameter of the opening 12a to the thickness of the barrier layer 14 is 50-2000. This standard gas barrier film 10 has a water vapor permeability of 10-6 to 10-3 g/m2/day at...
Ultrahigh gas barrier layers for water vapor and oxygen are coated on the plastic film to prevent the degradation of organic electronic devices. The ultrahigh gas barrier layers are required to show a WVTR of 10-6g m-2day-1level. Various WVTR measuring devices and methods have been proposed to...
Anaccepted unit of permeability is the metric perm centimeter, or1 g/m 2 per day per mm Hg·cm of thickness. The SI unit is themol/m 2 ·s·Pa·mm. The test conditions (see 3.1) must be stated.3.1.2 water vapor permeance—the ratio of a barrier’sWVTR to the vapor pressure ...
