本文介绍了聚（环氧乙烷）转化成一个单烯丙基胺的使用离子连接策略，并随后在制造多烯丙基胺盐酸盐（PAH）的多烯丙基多层膜（PEM）的使用。发现所得薄膜表现出反向尺寸选择性，其中相对大的CO2分子的渗透比He更有利。简要讨论了这种新方法的潜力，用于修改的体积性能的质子交换膜。
This paper describes the conversion of poly(ethylene oxide) into a polyelectrolyte by use of an ionic linker strategy, and its subsequent use in fabricating polyelectrolyte multilayers (PEMs) with poly(allylamine hydrochloride) (PAH). The resulting thin films were found to exhibit reverse size-selectivity, in which the permeation of a relatively large CO2 molecule was favored over He. The potential of this new approach for modifying the bulk properties of PEMs is briefly discussed.
