- Abstract
- In this investigation, we synthesized thermally curable polymers by mixing poly(vinyl phenol) (PVP) and a thermal-crosslinking agent (a methylated melamine-formaldehyde, MMF). These polymeric insulating films exhibit good chemical, physical, and electrical properties as dielectrics. Their insulating and dielectric properties depend on the MMF concentration. We fabricated plastic-based organic thin-film transistors (OTFTs) with these dielectric layers to investigate the relationship between the performance of the OTFT and the electrical/chemical properties of these insulating films. The OTFT showed good electrical performance; the field-effect mobility was 1.1 cm2V.1s.1. A dielectric layer with a relatively low dielectric constant was found to give a higher field-effect mobility.
