摘要：

以4-(3-苯基-4-羟基苯基)-2,3-二氮杂萘-1-酮(DHPZ-P)、 4-(4-羟基苯基)-2,3-二氮杂萘-1-酮(DHPZ)和1,4-二(4'-氟苯甲酰基)苯(BFBB)为原料, 经溶液亲核取代缩聚反应, 通过调节DHPZ-P和DHPZ的比例, 合成了一系列侧苯基杂萘联苯聚醚酮酮(PPEKK-P), 然后以浓硫酸为磺化剂, 制备出一系列磺化侧苯基杂萘联苯聚醚酮酮(SPPEKK-P). 利用傅里叶变换红外光谱(FTIR)和氢核磁共振谱(1H NMR)对聚合物结构进行表征, 结果表明, 磺酸基团引入到聚合物链的侧苯基上. 采用溶液浇铸法制备SPPEKK-P质子交换膜. SPPEKK-P膜的吸水率、 溶胀率和质子传导率均随离子交换容量(IEC)的增加而增加, 且具有较好的耐氧化性. IEC最高的SPPEKK-P-100膜的质子传导率在95℃能达到7.44×10-2 S/cm, 且甲醇渗透系数为5.57×10-8 cm2/s, 阻醇性能优于Nafion117膜.

Abstract:

Poly(phthalazinone ether ketone ketone)s with pendant phenyl groups(PPEKK-P) were synthesized via high temperature polycondensation from 4-(4-hydroxyphenyl)-2,3-phthalazin-1-ketone, 4-(3-phenyl-4-hydroxyphenyl)-2,3-phthalazin-1-ketone and 1,4-bi(4-fluorobenzoyl)benzene(BFBB). A series of sulfonated poly(phthalazinone ether ketone ketone)s containing pendant phenyl groups(SPPEKK-P) was prepared from PPEKK-P with concentrated sulfuric acid as the sulfonating agent. The chemical structures of PPEKK-P and SPPEKK-P were characterized by FTIR and 1H NMR. SPPEKK-Ps proton exchange membranes were obtained by solution casting method. Water uptake, swelling ratio and proton conductivities of SPPEKK-Ps membranes increased with the increase of ion exchange capacity. The membranes exhibited good oxidative stability. The methanol permeability values of SPPEKK-Ps membranes were much lower than that of Nafion117 membrane. The proton conductivity of SPPEKK-P-100 membrane reached 7.44×10-2 S/cm at 95℃.
