A barrier film is a fundamental component of the fast growing organic electronic device industry that is necessary to sustain long‐term stability. The barrier film prevents the permeation of environmental moisture and oxygen into the organic electronic device. Superior barrier property is the most crucial characteristic of a barrier film, in addition to a high refractive index. A high‐refractive‐index barrier film has the potential to reduce the refractive‐index mismatch between a device and a protective film, consequently, reducing the energy costs by increasing the light output. In this work, six epoxy and phenoxy resin composite compositions are synthesized separately, each with a different cross‐linker. POL‐TE1/PET and POL‐HD1/PET films show enhanced refractive indexes of 1.726 (at 750 nm) and 1.721 (at 500 nm), allowing only 71.7% and 70.4% permeation, respectively, compared to those of POL/PET, while exhibiting more than 80% transparency and excellent properties. The films are fabricated using a straightforward process, from a solution, at low temperature and under atmospheric conditions, using an applicator and bar coating.

用于有机电子产品的高折射率和高阻隔性环氧苯氧基阻隔膜

阻挡膜是快速发展的有机电子设备行业的基本组成部分，它是维持长期稳定性所必需的。阻挡膜防止环境湿气和氧气渗透到有机电子器件中。除了高折射率之外，优异的阻隔性能是阻隔膜的最关键特性。高折射率阻挡膜有可能减少设备和保护膜之间的折射率失配，从而通过增加光输出来降低能源成本。在这项工作中，分别合成了六种环氧树脂和苯氧基树脂复合材料组合物，每种组合物具有不同的交联剂。POL‐TE1 / PET和POL‐HD1 / PET膜的折射率分别提高到1.726（在750 nm处）和1.721（在500 nm处），分别只有71.7％和70。与POL / PET相比，渗透率分别为4％，同时具有超过80％的透明度和优异的性能。薄膜是在溶液中，在低温和大气条件下，使用涂敷器和棒涂剂，通过简单的工艺制成的。
