Few-seconds optical crosslinking of polymer gate dielectric using Intensely Pulsed White Light for efficient production of flexible organic thin film transistor |
| 초록 |
We demonstrated instantaneous optical crosslinking of polymer gate dielectrics on the flexible substrate using an intensely pulsed white light (IPWL). IPWL has many advantageous such as room-temperature processibility, short process times, large treatment area, R2R process compatibility. A few seconds irradiation of IPWL on representative polymer dielectric which consisted of poly(4-vinyl phenol) (PVP) with common crosslinking agent poly(melamine-co-formaldehyde) resulted in fully crosslinked PVP films which has smooth surfaces and low leakage current densities comparable to thermally crosslinked PVP at 180 ℃. Flexible OTFTs based on IPWL-crosslinked PVP showed good electrical performance with bending durability and uniformity over the large-area. |
