Abstract

The invention discloses a side chain type sulfonated polyaryletherketone sulfone / ZIF-67@GO composite membrane and a preparation method thereof. An alkyl long side chain with a sulfonic acid group is added to construct a hydrophilic / hydrophobic microphase separation structure, and then a metal organic framework filler is added to construct a well interconnected metal organic framework structure (ZIF-67@GO). According to the hybrid membrane, sulfonated polyaryletherketone sulfone (C-SPAEKS-DBS) containing carboxyl and double bonds is used as an organic matrix, 2-acrylamide-2-methylpropane sulfonic acid (AMPS) is used as a side chain, and ZIF-67@GO is used as a metal organic framework filler. Experiments show that the thickness of the prepared hybrid membrane is 90-110 [mu] m, the hybrid membrane shows excellent proton conductivity, and compared with pure C-SPAEKS-DBS-AMPS (0.0487 S / cm at the temperature of 30 DEG C and 0.0809 S / cm at the temperature of 80 DEG C) and C-SPAEKS-DBS-AMPS-1% ZIF-67@GO (0.0868 S / cm at the temperature of 30 DEG C and 0.1331 S / cm at the temperature of 80 DEG C), the proton conductivity is greatly improved and is about 1.7 times that of a pure membrane. Compared with a Nafion membrane, the proton conductivity of the hybrid membrane is increased by about 27%.
