Influence of solvents on the gas barrier properties of the organic coating layers containing epoxy resin |
| 초록 |
For the gas barrier films, which are attracting attention due to the commercialization of flexible devices, it is very important to develop a flat organic coating layer which can prevent gas permeation. To investigate the effect of solvents of the organic layers, coating solutions containing epoxy resin were prepared using various solvents and converted to thin layers on the PET film. Reactive monomers including 1,6-hexanediol diacrylate(HDDA), pentaerythritol triacrylate(PETA) were used as UV curable components and epoxy resin was used to increase barrier properties. Depending on the type of solvents, there is a difference in the amount of residual solvent after curing, and the residual solvent interferes with curing. In this experiment, solvent system of excess acetone in toluene was the best in terms of the gas barrier properties and this was the same tendency with residual solvent amount in coating layers. Various analytical methods were used to analyze barrier properties. |
