Abstract
A SPPO/IL composite membrane was obtained by self-assembly using the SPPO with the highest degree of sulfonation and the prepared ionic liquid (1-methyl-3-methylimidazolium). SPPO/IL composite membrane is doped with phosphoric acid to form SPPO/IL/PA composite membrane. The SPPO/IL composite membrane is immersed in PA for 24 h, the ion conductivity reaches 36.1 mS/cm. The mechanical stability (350°C), swelling (area 2.26%, volume 2.58%), and oxidation stability (4.2 h) are all acceptable. SPPO/IL/PA composite membranes have application potential as HTPEM materials. A sulfonated poly(2,6-dimethyl-1,4-phenylene oxide)/ionic liquid (SPPO/IL) composite membrane was obtained by self-assembly using the SPPO with the highest degree of sulfonation and the prepared ionic liquid (1-methyl-3-methylimidazolium). SPPO/IL composite membrane is doped with phosphoric acid to form SPPO/IL/PA composite membrane.
