摘要: 以发烟硫酸和4,4-二(4-氟苯甲酰基)苯[1,4-bi(4-fluorobenzoyl)benzene]为原料,通过磺化反应,制得磺化二氟三苯二酮[1,4-bi(3-sodiumsulfonate-4-fluorobenzoyl)benzene].利用亲核缩聚反应,调整磺化单体和非磺化单体的比例,与酚酞进行聚合,制取了具有不同磺化度的聚醚醚酮酮,并对聚合物的结构进行了表征.结果表明,此系列磺化聚醚醚酮酮的膜制品具有良好的离子交换特性,可望应用于燃料电池膜.

Abstract: A new sulfonated monomer 1,4-bi(3-sodium sulfonate-4-fluorobenzoyl)benzene was prepared by sulfonation of 1,4-bi(4-fluorobenzoyl)benzene with fuming sulfuric acid. Then a series of sulfonated PEEKKs derived from the monomer were synthesized via aromatic nucleophilic substitution polycondensation of phenolphthalein with different molar ratios of 1,4-bi(3-sodium sulfonate-4-fluorobenzoyl)benzene to 1,4-bi(4-fluorobenzoyl)benzene. The structure and property of the polymers were characterized and studied. Most of the polymers were easily cast into tough membranes. The membranes show a high ion exchange capacity and very good prospective in proton exchange membranes(PEM) usage.

Key words: Sulfonation, PEEKK, Fuel cell, Proton exchange membrane(PEM)
