摘要:
为得到高效低成本的质子交换膜材料,选用磷酸锆(ZrP)引入聚酰亚胺(PI)有机基体中制备PI/ZrP质子交换复合膜。利用红外吸收光谱表征复合膜结构,通过扫描电镜观察复合膜形貌,并对复合膜的含水率、溶胀度、热稳定性和质子传导性能进行研究。实验结果表明:ZrP均匀分散在质子交换复合膜中,ZrP的加入增强了质子交换复合膜的保水性能和热稳定性。PI/ZrP质子交换复合膜能提供稳定的质子传输通道,随着ZrP掺杂量的增加复合膜的质子电导率升高,在90 ℃、相对湿度为100%的环境中,PI/20%ZrP复合膜的质子电导率达到3.61×10-2 mS·cm-1。
Abstract:
In order to obtain proton exchange membrane with high efficiency and low cost, zirconium phosphate(ZrP)was doped into polyimide(PI)to prepare PI/ZrP proton exchange composite membranes. The chemical structures of composite membranes were characterized through Fourier transform infrared(FT-IR)spectra and the surface morphology was studied with scanning electron microscopy(SEM). Furthermore the thermal stability, water uptake, water swelling ratio and proton conductivity of the membranes were investigated. The results showed that ZrP was uniformly distributed into the proton exchange composite membranes. The water retaining capacity and thermal stability of the composite membranes had been improved with the increase of ZrP content. In addition, PI/ZrP proton exchange composite membranes can provide stable proton conductive pathways. The proton conductivity of composite membranes increased with increasing of the ZrP content and PI/ZrP 20% membranes exhibited the proton conductivity of 3.61×10-2 mS·cm-1 at 90 ℃ and relative humidity at 100%.
