The invention relates to phosphonic acid and 1,2,3-triazole functional polyether sulfone for a proton exchange membrane and a preparation method of phosphonic acid and 1,2,3-triazole functional polyether sulfone. An acidic group phosphonic acid and a basic group 1,2,3-triazole are connected to the same polyether sulfone chain, and direct hot-press film formation is carried out. The preparation process is simple, the raw materials are all industrial grade products and are low in price, and large-scale production is easy to achieve. The prepared acid-base amphoteric membrane has good proton conductivity and can be used for being applied to a proton exchange membrane fuel cell. 本发明涉及种质子交换膜用膦酸和1,2,3-三唑功能化聚醚砜及其制备方法。其酸性基团膦酸和碱性基团1,2,3-三唑连接在同聚醚砜链上，将其直接进行热压成膜。本发明的制备工艺简单，原材料皆为工业级产品，价格低廉，易于实现大规模生产。制备得到酸碱两性膜具有良好的质子电导率，可用于质子交换膜燃料电池的应用。
