Abstract:Hierarchical polyimides (PIs) not only show outstanding thermal stability and high mechanical strength but also have great advantages in terms of microstructure and surface area, which makes them highly valuable in various fields such as aerospace, microelectronics, adsorption, catalysis, and energy storage. However, great challenges still remain in the synthesis of hierarchical PIs with well‐defined microstructure. Herein, polyamide acid salts (PAAS) with tunable ionization degree are synthesized first via th… Show more
