Photocrosslinked polymer films with high optical transmittance and good thermal stability |
| 초록 |
We designed and synthesized new photocrosslinking prepolymers bearing both photoreactive acrylate and cinnamate double bond, which may be applied to many applications such as the field of the display technology. The prepolymers are expected to produce the photolithographic pattern with high transmittance and good thermal stability. Chemical structures of the prepared photocrosslinking prepolymers were confirmed by 1H-NMR and FT-IR spectroscopies. We investigated the photocuring kinetics of the prepolymers using FT-IR and UV-Vis spectroscopies, confirming excellent photoreactivity of the polymers. The photocrosslinking prepolymers were dissolved in the appropriate organic solvents with a photoinitiator and one of the red, green or blue pigments. The solution was spin-coated on a glass substrate, resulting in excellent quality of the thin film about 1 mm. The photocrosslinking prepolymer film was exposed by UV light through a quartz photomask and then developed in an appropriate solvent, leading to the excellent photolithographic pattern. We also confirmed superior thermal stability of photocured polymer film through the measurement of TGA and UV-Vis spectroscopy. |
