Title:
MODIFIED NB2CTX NANOSHEET MEMBRANE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/092809
Kind Code:
A1
Abstract:
A modified Nb 2CT x nanosheet membrane and a preparation method therefor. The preparation method comprises the steps of: adding a modifier into an Nb 2CT xMXene suspension and subjecting same to ultrasonic mixing, then uniformly distributing same on the surface of a polyvinylidene fluoride membrane by means of vacuum filtration to form a modified Nb 2CT x thin layer, drying same, and then separating the thin layer from polyvinylidene fluoride, wherein the modifier is a functional organic matter capable of providing hydroxyl and/or carboxyl. The basic concept of an ion transport behavior and a two-dimensional nanosheet surface modification method for selective ion separation are discussed. The mixed carboxyl and hydroxyl modified surface brings about a new way of thinking for the design of an ion selective membrane. The cognition of the transport of solvated ions in a nano limited two-dimensional channel is further improved, and the potential application thereof is explored. In contrast to a traditional size exclusion mechanism and cognition of low-selectivity of a 2D material-based membrane, the invention demonstrates an interconnected ionized water network in a membrane matrix under a high ion concentration.
