摘要
通过溶液共混的方法,以磺化聚醚醚酮(SPEEK)和聚醚砜(PES)为原料,N,N-二甲基甲酰胺(DMF)为溶剂,制备了一系列不同比例的SPEEK与PES的共混膜,并研究了膜的组成对膜的吸水率、电导率、甲醇渗透系数的影响,与目前所使用的Nafion117膜相比,这种共混膜既可以提高阻醇性能,同时又具有一定的电导率。
A series of blend membranes of both polytheretherketone (SPEEK) and polyethersulfone(PES) , The water uptake, proton conductivity and methanol barrier property as a function of the membrane compositions are discussed. Compared to the Nation 117 membrane currently used in dirdct methanol fuel cells (DMFC),this blend membranes are alcohol rejecting ability is better while a certain high conductivity is maintained.
