Most of the near commercial and prototype plastic electronics devices are built on plastic substrates and utilize organic materials that are sensitive to oxygen and moisture.
OLED lighting and displays, for example, require barrier properties that mean that the transfer of moisture through the barrier must be around 1x10-6gm-2day-1. If the barrier does not perform to this specification, the product life is significantly reduced. Other applications such as organic PV and transistor arrays using organic and inorganic materials are equally as sensitive to the permeation of gases and moisture through the plastic substrate. If the barrier challenge is not met, then many of products placing electronics on plastic will never be commercially viable.
On 24 September the Knowledge Transfer Network and the Institute of Physics Printing and Graphics Science Group are hosting a one-day technical conference on the advances in the production of and characterisation of ultra-high barriers for plastic electronics.
