Summary on Grant Application Form |
The project will investigate the feasbility of producing very high quality barrier films in MOCON test formats for next
generation flexible OLED and plastic logic display applications.These exhibit ultra low water vapour transfer rates (WVTR)
of less than 1 X 10-5 g/m2 per day using self healing layers of high quality CVD graphene and Atomic Layer Deposited
(ALD) amorphous alumina. The work will explore the neccessary industrial process parameters to ensure the lowest price
point at which the minimum barrier properties can be delivered for the chosen high end application. These resultant
polymer supported barrier films will then be benchmarked against existing barrier coatings in WVTR and mechanical flex
tests. These measurements will also be made traceable by the National Physical Laboratory (NPL) to ensure that the data
claims are correct and meaningful comparisons can be made. The industrial innovation challenge will be producing this
fully flexible, self-healed (contiguous), optically transparent film of 25cm2 (beyond the current state of art 4cm2) in a timely
manner with very few acceptable defects to ensure ultra-barrier performance. The project will utilise advanced
characterisation metrologies and quality control analysis to ensure the iterative development of the films and the resultant
understanding gained from the feasibility studies will be used to model and anticipate future larger film systems and will
also be exploitated where possible by barrier seeking end users and through joint KTN activities to target these
communities.
