제목 Fluorinated Organic-Inorganic Nanohybrid Sol-Gel Derived Gate Dielectrics for Ultra-Flexible and Electrical Stable Organic Electronics
초록 A new fluorinated organic–inorganic (O–I) hybrid sol-gel-based material was successfully synthesized and applied as a gate dielectric layer in flexible organic thin-film transistors (OTFTs). The three-arm-shaped alkoxysilane-functionalized amphiphilic polymer yielded an uniformly dispersed and stable O–I hybrid material through the formation of an emulsion. Here, a fluorinated precursor was introduced into the system, making it possible to realize highly stable spherical nanoparticles; this enabled long-term colloidal stability (~1.5 years) owing to the presence of fluorine groups with intrinsically strong repulsive forces. Additionally, the FAGPTi film was facilely deposited via thermally annealed sol-gel reactions; the films exhibited enhanced insulating properties with excellent flexibility, and were applied to OTFT with stable operation properties. Moreover, practical logic devices were successfully conducted with these FAGPTi-based OTFTs.
