Synthesis and Properties of Sulfonated Polyether Ketone/Barium Titanate Proton Exchange Membrane

Keywords： barium titanate , sulfonated polyether ketone , proton exchange membrane

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.
