Eco-friendly water-borne polyimide gate insulators for large area OFETs arrray using simple bar-coating method |
| 초록 |
Here, we successfully demonstrate large-area OFET arrays with water-borne PI gate dielectrics via a simple bar-coating process. The poly(amic acid) salt (PAAS) as a precursor of PI polymerized in water as a non-toxic solvent, which has hydrolytic stability and low-imidization temperature below 250 oC, was well coated on the substrates with smooth surface morphology. The thickness of PI thin film as gate dielectric was precisely controlled between a few tens of nanometers and hundreds of nanometers via the concentration of the polymer solution and wire diameter of bar, bar pulling speed. As a results, a large-area OFET arrays with water-borne PI gate dielectrics were successfully fabricated by simple bar-coating process and showed excellent device‐to‐device performance uniformity in 4 inch transistor arrays. |
