| 英文摘要 | Thermoplastic polyimides (TPIs) exhibit favorable processing capabilities, and meanwhile preserve most of the superior properties of PIs, such as excellent heat resistance, insulation performance, chemical stability and so on. TPI can be obtained by incorporating flexible linkages and side groups. However, it would lead to either flexible polymer chains or weakened intermolecular interaction, causing the decline in thermal stability. Herein, we develop TPIs with good thermal stability through the introduction of an N-butyl-N-phenylaniline group. Its flexible linkage-N-and the twisted structure are conducive to achieving flexible polymer chains and increasing free volume, respectively, leading to good thermoplasticity. Simultaneously, the N-butyl-N-phenylaniline group, as electron-rich aromatic moiety in the diamine monomer, is able to maintain strong charge transfer complex (CTC) effect, beneficial for preserving high thermal stability. As a result, the as-prepared TPI exhibits good thermoplasticity as well as a high Tg of 357 degrees C. |
