Solution-based TiO2-polymer composite dielectric for low operating voltage OTFTs.
The cross-linking reaction of a TiO(2)-polymer composite (TPC) dielectric with poly(4-vinyl phenol) (PVP), a TiO(2) 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 TiO(2) precursor.
