摘要：

Poly(vinyl acetate) (PVAc) is currently being investigated as a potential polymeric gate insulator for organic thin film transistors (OTFTs), because it can be easily converted from poly(vinyl alcohol) through hydrolysis and can form a composite material with inorganic particles. In addition, the PVAc with a dielectric constant of 3.2-9.3 can be adopted as a good gate insulator for the OTFTs. We report characteristics of the electric transport of pentacene based OTFT using PVAc material with and without organic montmorillonite (OMMT) layer as a polymeric gate insulator. Spin coating condition of the gate insulator with PVAc was measured considering both viscositiy of PVAc dissolved in chloroform as a function of PVAc concentration and surface morphology after the spin coating process.
