阅读说明:本技术 通过uv引发的聚合的离子交换膜 (Ion exchange membranes by UV initiated polymerization ) 是由 乔治·顾 萨瓦斯·哈德吉基里亚库 西蒙·P·杜克斯 迈克尔·J·肖 于 2019-09-25 设计创作,主要内容包括:公开了生产离子交换膜载体的方法。该方法包括用带电荷的单体溶液使聚合物微孔基底饱和,所述带电荷的单体溶液包含至少一种官能单体、交联剂和有效量的至少一种光聚合引发剂;以及通过在有效地使至少一种官能单体交联并产生离子交换膜载体的条件下将饱和的聚合物微孔基底暴露于紫外光来使至少一种官能单体聚合。还公开了生产单价选择性离子交换膜的方法。该方法包括用带电荷的化合物层将离子交换膜载体的外表面官能化,干燥离子交换膜载体,以及将离子交换膜载体浸泡在包含酸或碱的溶液中持续有效地产生单价选择性离子交换膜的时间量。(A method of producing an ion exchange membrane support is disclosed. The method comprises saturating a polymeric microporous substrate with a charged monomer solution comprising at least one functional monomer, a crosslinking agent, and an effective amount of at least one photopolymerization initiator; and polymerizing the at least one functional monomer by exposing the saturated polymeric microporous substrate to ultraviolet light under conditions effective to crosslink the at least one functional monomer and produce the ion-exchange membrane support. Also disclosed is a method of producing a monovalent selective ion exchange membrane. The method includes functionalizing an outer surface of an ion exchange membrane support with a layer of a charged compound, drying the ion exchange membrane support, and soaking the ion exchange membrane support in a solution comprising an acid or a base for an amount of time effective to produce a monovalent selective ion exchange membrane.)
