Blended polymer as composite insulating layers for organic field effect transistor

Impact of polymer chemistry on the application of polyurethane/ureas in organic thin film transistors

“…CYTOP), polyvinyl alcohol (PVA), polystyrene (PS), polyimide (PI), poly(vinylphenyl) (PVP), PUU, etc. [51][52][53][54][55] Among them, PUU has gained increasing attention from researchers as an insulating layer in OTFTs recently, due to its excellent mechanical properties, high dielectric constant and wide adjustable performance. This work could be traced back to the related report of Murata et al in 2007, which used dipolepolarized PUA as the gate insulator layer to regulate the threshold voltage of OTFTs.…”
