Photo‐Curable Polymer Blend Dielectrics for Advancing Organic Field‐Effect Transistor Applications
Abstract:A solution method of photo‐curable and ‐patternable polymer gate dielectrics was introduced by using blend solutions of poly(4‐dimethylsilyl styrene) (PDMSS) and poly(melamine‐co‐formaldehyde) acrylate (PMFA). The fabrication was optimized to produce a smooth hydrophobic gate dielectric with good insulating and solvent‐resistant properties. On the optimized PDMSS/PMFA blend gate dielectric, pentacene could grow into highly ordered structure, showing high electric performances for the resulting OFETs, as well as PTCDI‐C13 and TES‐ADT.
