The UK launched a new project called Gravia that aims to investigate the feasibility of producing graphene-based encapsulation films for next generation flexible OLED lighting and display products.

The Gravia project is a 12-month effort, and the partners in the project expect to deliver a feasible material and process system by the project's end. Drawing on the unique properties of graphene, 'Gravia' will aim to achieve barrier materials that are not only flexible, but also transparent, robust, and very impervious to many molecules.

The key challenge will be to develop large-area poly-crystalline graphene films which maximize performance while mitigating process imperfections. In this way, solutions can be produced at scale and economically viable in the future.
