Abstract：

Non-fluorinated sulfonic acid proton exchange membranes represented by sulfonated polyether ether ketone (SPEEK) have become a research hotspot due to their advantages such as low cost and excellent heat resistance. However, it is difficult to synergistically optimize their ionic conductivity, stability and durability. With its high mechanical strength and chemical stability, polyimide (PI) has become an ideal material for the composite modification of SPEEK. This work was carried out in three aspects: the controllable synthesis of polyamic acid (PAA), the preparation of PI nanofiber membranes, and the research on the composite proton exchange membranes with a PI/SPEEK/PI sandwich structure. The preparation processes of the PAA solution and the PI fiber membrane have been successfully explored, and the proton conduction performance of the composite membrane has been significantly improved. Molecular simulation results indicated that the hydrogen bonding interaction between the amide bond of PI and the sulfonate group of SPEEK was the keypoint to interface optimization. This study provides a new path for improving the performance of non-fluorinated proton exchange membranes.
