Abstract Barrier or encapsulate films are indispensable components of organic electronic devices. The stability of organic electronic devices strongly depends on the efficiency of these barrier films, for they prevent device degradation and moisture penetration in the device. In this study, a hybrid composite multilayer film, comprising an interactive composite layer sandwiched between two composite organic layers, was devised. The middle interactive composite layer (COMM) comprised inorganic montmorillonite dispersed throughout an epoxy and phenoxy polymer (POL) matrix. The external organic composite layers (POL-EZ) consisted of POL and the newly synthesized eugenol benzoxazine (EZ) composite. The new multilayer film exhibited excellent transparency, tensile strength, chemical resistance, and stability. The POL-EZ/COMM/POL-EZ/PET film (where PET denotes polyethylene terephthalate and was used as the substrate) exhibited a remarkable moisture permeation rate of 7.140 × 10−3 gm-2 day-1. Moreover, the multilayer film could be easily processed via roll-to-roll coating processes. Thus, the newly fabricated barrier film is an exceptional candidate for commercialization as barrier films for organic electronic devices.

具有有机和交互材料的高阻隔聚合物多层膜

摘要 阻隔或封装薄膜是有机电子器件不可或缺的组成部分。有机电子器件的稳定性在很大程度上取决于这些阻隔膜的效率，因为它们可以防止器件退化和水分渗透到器件中。在这项研究中，设计了一种混合复合多层膜，包括夹在两个复合有机层之间的交互式复合层。中间交互复合层 (COMM) 包含分散在环氧树脂和苯氧基聚合物 (POL) 基质中的无机蒙脱石。外部有机复合层 (POL-EZ) 由 POL 和新合成的丁香酚苯并恶嗪 (EZ) 复合材料组成。新的多层薄膜表现出优异的透明度、拉伸强度、耐化学性和稳定性。POL-EZ/COMM/POL-EZ/PET 薄膜（其中 PET 表示聚对苯二甲酸乙二醇酯并用作基材）表现出显着的水分渗透率为 7.140 × 10-3 gm-2 day-1。此外，多层薄膜可以通过卷对卷涂布工艺轻松加工。因此，新制造的阻隔膜是作为有机电子器件阻隔膜商业化的绝佳候选者。
