SELF-ORGANISED MATERIALS FOR FLEXIBLE ELECTRONICS
Grant number: FT130100500 | Funding period: 2014 - 2018
The emergence of organic electronics is transforming current electronic technologies that will lead to light-weight flexible devices such as foldable displays, building-integrated lighting and low-cost solar cells. The greatest improvements in efficiency and durability of devices will be achieved through precise control of material structure from molecular to bulk scales. This project will address this problem by designing smart materials that can self-organise and enhance the properties required for specific applications. New insights will be acquired in structure-property-function relations and successful concepts will be used to assemble well-defined macroscopic materials in organic elect..View full description
