Preparation and characterization of chloromethylated/quanternized poly (phthalazinone ether sulfone) anion exchange membrane
چکیده انگلیسی
Chloromethylated poly (phthalazione ether sulfone) (CMPPES) material was prepared with chloromethyl ether as chloromethylating regent and sulfuric acid as solvent. The effect of chloromethyl ether quantity on the chlorinity degree of chloromethylation (DCM) of CMPPES was investigated. DCM of CMPPES was in the range of 1.94-2.89 mmol/g. CMPPES were identified with 1H NMR and TGA. Compared with PPES, the thermal stability of CMPPES decreases obviously. The CMPPES was dissolved in NMP (10 wt%) and cast on glass to form a membrane. The final anion exchange membranes were prepared by soaking CMPPES in trimethylatine (33%) to aminate. Ion-exchange capacity (IEC), water content, dimensional stability and membrane area resistance of the anion exchange membranes were investigated. It was found that IEC of final anion exchange membrane was between 1.38 and 2.12 mmol/g, and water content of anion exchange membrane increased with an increase of IEC, however, dimensional stability and area resistance of membranes for 2 M VOSO4 in 3 M H2SO4 solution decreased. The area resistance was lower than Nafion112.
