| 中文摘要 | a series of sulfonated polymides containing benzimidazole groups were synthesized using 4,4'-binaphthyl-1,1',8,8'-tetracarboxylic dianhydride (btda), 4,4'-diaminodiphenyl ether-2,2'-disulfonic acid (odads) as the sulfonated diamine, and 2-(3',5-diaminophenyl)benzimidazole (a) or 6,4'-diamino-2-phenylbenzimidazole (b) as the nonsulfortated diamine. the electrolyte properties of the synthesized polyimides ia-x, ib-x, x refers to molar percentage of the sulfonated diamine) were investigated and compared with those of polyimides (ic-x) from btda, odads, and m-phenylenediamine (c). all synthesized polyimides possessed high molecular weights revealed by their high viscosity, and formation of tough and flexible membranes. polyintides with benzimidazole groups exhibited much better swelling capacity than those without benzimiclazole groups. this was attributed to the strong interchain interaction through basic benzimidazole functions and sulfonic acid groups. the sulfortated polyimides that are incorporated with 1, 1',8,8'-binaphthalimide exhibited better hydrolytic stability than that with 1,4,5,8-naphthalimide. polyimide membranes with good water stability as well as high proton conductivity were developed. polyimide membrane (ia - 90), for example, did not lose mechanical properties after being soaked in boiling water for tooo h, while its proton conductivity was still at a high level (compared to that of nafion 117). |
