Synthesis of Highly Self-healable and Weatherable Polymers based on Charge Transfer Complex (CTC) Interaction |
| 초록 |
Series of self-healable polymers based on charge transfer complex (CTC) interaction are synthesized and their self-healability and weatherability are examined in this study. The self-healable polymers are prepared from functional polyimides, where 3,3',4,4'-biphenyl tetracarboxylic acid dianhydride (BPDA), pyromellitic dianhydride (PMDA), or 4,4'- oxydiphthalic dianhydride (ODPA) is introduced to control the degree of CTC and UV-resistance. All the self-healing efficiencies increase with higher molar ratio of BPDA, PMDA, or ODPA owing to the stronger CTC interaction. However, the self-healable polymer containing BPDA only shows that ΔYI (change in yellow index before and after UV exposure) decreases considerably as the molar ratio of BPDA increases while other self-healable polymers show the opposite trend. The self-healable polymer prepared in this study shows excellent self-healability and weatherability, which explains its feasibility to be widely used for outdoor applications. |
