摘　　要：近年来,由无机二维材料氧化石墨烯(GO)构筑的纳滤膜因其显著的渗透和分离性能而备受关注.其中,GO纳滤膜内部典型的二维传输通道成为了决定其权衡上限的关键因素.插层法作为一种灵活便捷的改性方式已被证明可用于调控GO纳滤膜的层间通道性能.但根据插层材料种类和性质的不同,其对GO纳滤膜的综合性能会产生一定影响.因此,本文从GO纳滤膜的层间通道调控出发,强调了插层技术的独特优势.并根据插层材料的属性将其分为刚性纳米材料和柔性纳米材料两大类,详细分析了各类材料在对GO纳滤膜进行插层时结构和性能上的影响.同时,也提出了插层法在制备GO纳滤膜时目前所面临的一些困难和挑战,并对未来的研究方向做出了展望,旨在为设计具有出色稳定性和高分离性能的GO纳滤膜提供参考和借鉴.In recent years,nanofiltration membranes constructed from the inorganic two-dimensional material graphene oxide(GO)have attracted much attention due to their remarkable permeation and separation properties.Among these,the typical two-dimensional transport channel inside the GO nanofiltration membranes have become a key factor in determining the upper limit of their trade-off.Intercalation,as a flexible and convenient modification method,has been proven suitable for regulating the interlayer channel properties of GO nanofiltration membranes.However,the different types and properties of intercalation materials can impact the overall performance of GO nanofiltration membranes.This paper emphasizes the unique advantages of intercalation technology from the perspective of interlayer channel regulation in GO nanofiltration membranes.It also classifies the intercalated materials into two categories,rigid nanomaterials and flexible nanomaterials organic polymers,according to their properties,and analyses in detail the effects of each type of material on the structure and performance of GO nanofiltration membranes when intercalated.Additionally,we highlight the difficulties and challenges in the preparation of GO nanofiltration membranes using the intercalation method and provide an outlook on future research directions.This study aims to offer a reference for designing GO nanofiltration membranes with excellent stability and high separation performance.
