Abstract |
A new self-healable polymeric material based on supramolecular chemistry is synthesized and its self-healing properties are examined in terms of charge transfer complex (CTC) interaction. The self-healable polymeric material used in this study is prepared from polyimides, where CTC is formed through electronically-complementary interaction between dianhydride and diamine groups in polyimide chains. The self-healing behaviors are attributed to the strong supramolecular networks resulting from the intramolecular and intermolecular CTC interactions of polyimide chains. The self-healable material based on polyimides shows excellent self-healing capabilities and fast self-healing kinetics, which explains its feasibility to be widely used for self-healing applications. |
