Design and synthesis of self-healable polymeric coating materials with enhanced weatherability |
| 초록 |
We report the synthesis and characterization of new self-healable and weatherable polymeric coating materials. The self-healable polymeric materials are prepared by blending functional polyimides (fPIs) and conventional polyurethanes (cPUs) and have excellent self-healing properties due to the strong interaction between the charge transfer complex (CTC) in fPIs and the hydrogen bonding group in cPUs. The self-healable polymeric blends with 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA) moiety in fPIs show better weatherability compared with those with pyromellitic dianhydride (PMDA) or 4,4′-oxydiphthalic anhydride (ODPA), which is mainly attributed to the biphenyl structure of BPDA. The polymeric coating materials prepared in this study can be utilized as effective self-healing materials for outdoor applications since they exhibit excellent self-healing capability and weather-proof ability. |
