The project will investigate the feasbility of producing very high quality barrier films in standard test formats for high quality flexible encapsulation of OLED and plastic logic display applications.These exhibit ultra low water vapour transfer rates (WVTR) of less than 1 X 10-6 g/m2 per day using self healing multilayers of high quality CVD graphene and Atomic Layer Deposited (ALD) amorphous alumina multilayers. The work will explore the neccessary industrial process parameters to ensurelowest price point at which the minimum barrier properties can be delivered The resultant barrier films will be benchmarked against existing barrier coatings in WVTR and mechanical flex tests. The industrial innovation will be producing a fully flexible, self-healed (contiguous), optically transparent film of 25cm2 (beyond the current state of art 4cm2) using advanced characterisation and quality control metrologies to ensure iterative development. The resultant understanding gained from the feasibility studies will be used to model and anticipate future larger film systems and will be also exploitated where possible by barrier seeking end users and through joint KTN activities to target these communities.

该项目将研究以标准测试格式生产高质量屏障膜的可行性，用于OLED和塑料逻辑显示应用的高质量柔性封装。使用高质量CVD石墨烯和原子层沉积（ALD）非晶氧化铝多层自修复层，这些材料具有超低的水蒸气传输速率（WVTR），每天小于1 X 10-6 g/m2。这项工作将探索必要的工业工艺参数，以确保最低的价格点，在最低的屏障性能可以交付。所得的屏障膜将在WVTR和机械弯曲测试中与现有的屏障涂层进行基准测试。工业创新将使用先进的表征和质量控制计量技术来生产25cm2的完全柔性、自愈合（连续）、光学透明薄膜（超过目前的4cm2），以确保迭代开发。从可行性研究中获得的结果将用于模拟和预测未来更大的薄膜系统，并将在可能的情况下通过寻找最终用户和通过联合KTN活动针对这些社区进行开发。
