초록
Chemically and thermally stable, durable, thermal-cured polyacrylates having a hydrophobic nature, which were prepared by mixing polyacrylate having reactive sites and functional-anhydride, exhibit good insulation properties and high breakdown voltage (> 4.0혻MV/cm) as a dielectric. Plastic-based organic thin-film transistors with the thermal-acryl dielectric layer showed typical current-voltage characteristics; the field-effect mobility was calculated to be 0.22혻cm2 V- 1 s- 1, while the threshold voltage was approximately - 8혻V. It has been found that thin dielectric layers gave higher field-effect mobility. © 2007 Elsevier B.V. All rights reserved.
