Fundamental investigation of self-healable polymeric films based on charge transfer complex interaction |
| 초록 |
The self-healable polymeric films with charge transfer complex interaction are prepared by solution blending of conventional polyurethanes (cPUs) with functional polyimides (fPIs). The blended films have better self-healing properties compared with those of pure cPUs due to the synergetic effect between the charge transfer complex interaction in fPIs and the hydrogen bonding in cPUs. Furthermore, the blended films show both faster self-healing kinetics and higher surface hardness compared to those of pristine cPUs, which comes from the thermal-induced migration of fPIs chains toward the top surface of blended films during the film formation process. The polymeric films prepared in this study exhibit outstanding self-healing capabilities and mechanical properties, and therefore can be used for practical applications like automotive coatings and electronic devices. |
