Preparation method of acid-base double-layer core-shell nanotube/SPEEK composite proton exchange membrane

The invention relates to a preparation method of an acid-base double-layer core-shell nanotube/SPEEK composite proton exchange membrane. The method prepares an acid-base double-shell nano tube by a continuous two-step distillation-precipitation polymerization method, PMAA is selected as an inner shell polymer because the PMAA has a carboxylic group and has a high hydration energy and water absorbing capacity, PVI is selected as an outer shell polymer to enhance the dispersity of the nano tube in the matrix and optimize the proton transfer carrier so as to improve the proton conductivity. The preparation method provided by the invention can overcome the problems that an SPEEK membrane is poor in mechanical property caused by easy water loss or easy swelling in water under the high temperature and the low humidity, and ensures the high proton conductivity, high water retention and good dimensional stability of the composite PEM. 本发明为一种酸碱双层核壳纳米管/SPEEK复合质子交换膜的制备方法。该方法通过连续两步蒸馏-沉淀聚合方法制得酸碱双壳纳米管，内壳聚合物选择PMAA，由于PMAA具有羧
