“…Ethylene vinyl alcohol (EVOH) copolymer is a widely used packaging material in food industry, due to its good oxygen barrier and aroma permeability properties. Its low permeability is a result of the ethylene present in the polymer [1]. Packaging materials with low permeability to gases and water vapor improve shelf life.…”

In this study, ethylene vinyl alcohol copolymer (EVOH) nanocomposite was prepared by adding nano zinc oxide (nano-ZnO) as a filling agent and glycerol as a plasticizer. In the solution mixing method, usually a plasticizer is used to prevent the film from becoming brittle. However, adding a plasticizer also has adverse effects on the film. Examples of such effects include; decreased barrier properties (water vapor permeability and oxygen permeability) and reduced mechanical properties (tensile strength (TS)). The goal of this study was, to reduce the adverse effects of the plasticizer on film's matrix by adding nanoparticles. Three concentrations (0%, 1%, and 2%) of Nano-ZnO were used in order to find the optimum concentration of glycerol (30%, 40%, and 50%) with the least significant adverse effect. Incorporating glycerol reduced the barrier and the tensile strength properties in matrix films, while, adding nano-ZnO improved barrier, tensile strength properties and reduced adverse effects of the glycerol. FE-SEM image analysis was used to confirm the adverse effects of glycerol on matrix film.

“…Ethylene vinyl alcohol (EVOH) is one of the best known oxygen barrier materials in use today, with excellent gas barrier properties, processability, and sensitivity to moisture [1][2][3]. The permeation of oxygen and water vapor can lead to damage in electronic devices and the decomposition of foods.…”

We prepared ethylene vinyl alcohol (EVOH)/graphene oxide (GO) membranes by solution casting method. X-ray diffraction analysis showed that GOs were fully exfoliated in the EVOH/GO membrane. The glass transition temperatures of EVOH were increased by adding GOs into EVOH. The melting temperatures of EVOH/GO composites were decreased by adding GOs into EVOH, indicating that GOs may inhibit the crystallization of EVOH during non-isothermal crystallization. However, the equilibrium melting temperatures of EVOH were not changed by adding GOs into EVOH. The oxygen permeability of the EVOH/GO (0.3 wt%) film was reduced to 63% of that of pure EVOH film, with 84% light transmittance at 550 nm. The EVOH/GO membranes exhibited 100 times better (water vapor)/(oxygen) selectivity performance than pure EVOH membrane.

“…The diffusion equation is solved analytically and numerically, and the asymptotic behavior is discussed in detail. Gas permeation through polymer composites has been studied for long time [3][4][5][6][7][8][9][10][11][12][13] , but its analysis has been based on the assumption of the steady state. Since the steady state is not reached within the device lifetime during the normal operation of gas barrier edge seals for organic electronics, as discussed in the following, the present results significantly differ from those of previous studies and various implications can be discussed.…”

Materials and structures for water vapor barrier sealing are now actively studied, as the commercialization of organic electronic devices has become a reality. In this paper, we focus on the edge sealing barriers, in which diffusion plays an essential role. In the past, the diffusionlimited gas barrier properties were analyzed in the steady-state approximation, which is never reached within the device lifetime in the application for organic electronics. We analyze them using a simple analytical model. The diffusion before reaching the steady state is a strongly nonlinear process, as is well known, and the length scale of approximately 1 -10 mm is very important when a practical polymer resin is used for the edge seal.
