Solution-Based TiO2-Polymer Composite Dielectric for Low Operating Voltage OTFTs
The cross-linking reaction of a TiO2 polymer composite (TPC) dielectric with poly(4-vinyl phenol) (PVP), a TiO2 precursor, and poly(melamine-co-formaldehyde) is demonstrated: We suggest that the dense chemical structure of TPC is caused by the alkoxyl group of the PVP cross-linker, poly(melamine-co-formaldehyde) methylated/butylated, reacted with the hydroxyl group of the PVP and the ligands of the TiO2 precursor.
