本发明属于质子交换膜领域，公开了种三元复合质子交换膜及其制备方法。该三元复合质子交换膜以以磺化度为20～90％的磺化聚醚醚酮作为膜基质，掺杂季铵盐离子液体和纳米SiO溶胶。该三元复合质子交换膜将离子液体TEAS或TEAP锚定在复合膜内，并且通过原料的特定配比，在预防离子液体的流失的同时，保证了该三元复合质子交换膜的电导率及机械性能；采用溶胶～凝胶法制备纳米SiO溶胶，最后采用溶液浇铸法制备SPEEK/季铵盐类离子液体/纳米SiO三元复合质子交换膜，每步制备过程独立，可以同时进行，缩短时间，易于工业化生产。 The invention belongs to the field of a proton exchange membrane, and discloses a ternary composite proton exchange membrane and a preparation method therefor. The ternary composite proton exchange membrane takes sulfonated polyether ether ketone with the sulfonation degree of 20-90% as the membrane substrate; then quaternary ammonium salt ionic liquid and nanometer SiO sol are doped. According to the ternary composite proton exchange membrane, the ionic liquid TEAS or TEAP is anchored in the composite membrane; through the special matching of raw materials, the ionic liquid loss is prevented and the conductivity and the mechanical performance of the ternary composite proton exchange membrane are ensured; the nanometer SiO sol is prepared by a sol-gel method
