带电二维聚酮烯胺膜通过电荷调控纳米通道实现单价阳离子选择性传输
Selective Monovalent Cation Transport in Two‐Dimensional Polymer Membranes via Charge Control of Nanochannels
AI 导读
研究者在液–液界面制备了带电荷的聚酮烯胺基二维聚合物膜（2DPMs），其具有高结晶度和由酰基肟基团功能化的pH响应准一维多孔通道，通过改变膜电荷调控阳离子与通道的相互作用。
推荐理由
原文给出带电二维聚酮烯胺膜在K⁺/Li⁺分离上的渗透速率与扩散系数，可对照现有膜的上限判断其位置。
创新点
用膜电荷工程调节阳离子与通道的相互作用，在带正电的二维聚酮烯胺膜上同时获得高K⁺渗透速率与K⁺/Li⁺选择性，扩散系数超过现有石墨烯基和聚合物基膜。
