摘要:

将纳米钛酸钡(BT)在环己烷中超声分散制得均匀的悬浊液后,与磺化聚醚酮的二甲亚砜溶液均匀混合,然后采用流延法制备了掺杂质子交换膜。 通过环镜扫描电子显微镜表征发现BT在膜中分散均匀,通过吸水率、溶剂吸收率、尺寸变化、电导率、甲醇透过率、力学性能及稳定性等测试发现掺杂膜虽然电导率有所下降,但是其抗溶胀性、稳定性和力学性能显著提高。

关键词: 纳米钛酸钡, 磺化聚醚酮, 质子交换膜

Abstract:

To prepare sulfonated polyether ketone/barium titanate(SPAEK/BT) hybrid membrane, the mixture containing BT suspension in cyclohexane obtained under ultrasonic condition and dimethyl sulfoxide solution of SPAEK was casted onto the glass plates. The uniform dispersion of BT in the hybrid membrane was confirmed via SEM. The properties of the corresponding hybrid membranes, such as water uptake, solvent uptake, size change, proton conductivity, methanol permeability, mechanical properties, and stabilities were investigated. Compared to blank membrane, the anti-swelling, thermal stability, and oxidative stability of hybrid membranes are improved respectively. The water stability and mechanical properties are also improved, whereas the proton conductivity of the hybrid membrane is decreased in some extent.

Key words: barium titanate, sulfonated polyether ketone, proton exchange membrane
