摘要

提出了一种利用杂化纳米纤维来制备高性能质子交换膜的方法

首先采用溶液喷射纺丝技术纺制了SPES/SiO2杂化纳米纤维

再通过溶液浸渍法制备了SPES/SiO2/Nafion复合质子交换膜

并研究了其热稳定性、吸水性能、溶胀性能、质子传导性能以及甲醇渗透性能等.结果表明

杂化纳米纤维的引入明显改善了Nafion膜的热性能、尺寸稳定性

并大大提高了其质子传导性能.TG 数据表明复合膜的热稳定性相比于Nafion膜得到了极大改善.复合膜溶胀率均比Nafion膜的小

SPES/SiO2/Nafion-5

SPES/SiO2/Nafion-15和SPES/SiO2/Nafion-25在 80 ℃ 溶胀率仅为14.9%

15.84% 和 17.2%

但是复合膜的溶胀率随着SiO2含量的增加而增大.复合膜电导率随SiO2含量的增加呈先增大后减小的规律

SiO2含量为15%的复合膜在80 ℃、100%湿度条件下

质子导电率可达到0.154 S/cm.其阻醇性能也得到了极大改善

SiO2含量为25%的复合膜相比于Nafion膜其甲醇渗透率降低了55.3%.因此SPES/SiO2杂化纳米纤维复合质子交换膜可以作为一种新型质子交换膜应用于燃料电池中.

Abstract

Sulfonated poly(ether sulfone) (SPES)/Silica (SiO2) nanofibers were prepared by solution blowing process

and impregnated to Nafion matrix to prepare SPES/SiO2/Nafion composite proton exchange membranes (PEMs).The characteristics of the composite membrane

such as morphology

thermal stability

proton conductivity and performance of membrane as PEMs

were investigated.The results showed that the introduction of solution-blown nanofibers to composite membranes significantly improved properties of Nafion.The TG results showed all the composite membranes had better thermal stability than pure Nafion.Swelling ratios of all the composite membranes were lower than that of pure Nafion

and those of SPES/SiO2/Nafion-5

SPES/SiO2/Nafion-15 and SPES/SiO2/Nafion-25 were 14.9%

15.84% and 17.2% at 80 ℃

respectively.However

the swelling ratios of composite membranes increased with the increase of SiO2 content in nanofiber.Proton conductivity of the composite membranes increased first and then decreased with the increase of SiO2 content

and the membrane containing 15% SiO2could get 0.154 S/cm at 80 ℃ and 100% humidity.Besides

the methanol resistance was also greatly improved

methanol permeability of the composite membrane containing 25% SiO2decreased by 55.3% compared to that of Nafion.Therefore

the composite membrane containing hybrid SPES/SiO2 nanofibers can be considered as a promising PEM for fuel cell applications.
