Novel UV cross-linkable polymer dielectric for printable electronics

Marius G. Ivan, Yanguang Zhang, Neil Graddage & Ye Tao
Availability of solution processable materials is of paramount importance for fabrication of flexible electronics in roll-to-roll lines with high throughput and acceptable cost. We have developed and tested a novel UV cross-linkable polymer dielectric, and characterized it in all-flexo printed capacitors and TFTs. The cross-linking and polymerization are triggered by photo-generated free radical initiators, under open air and at room temperature upon exposure to ultraviolet radiation. The calculated dielectric constant at 100 KHz is 5.12,...
