We report the UV curing of poly(4-vinylphenol) (PVP), which is a widely used polymer dielectric for flexible organic field-effect transistors. OFETs with UV cured PVP dielectric outperformed the classical long-term high temperature annealed PVP OFETs in electrical performance with lower hysteresis, lower threshold voltage shifts in 100 continuous transfer scans and lower normalized drain current decay when bias stressed for 1 h. © 2019 IEEE.
