“…Multilayer graphene oxide membranes (GOMs) show superiority in scalability, chemical, and physical stability, and they are compatible with current membrane‐based technologies. [ 10 ] Thus, they attract broad research interest and boost various applications in water purification and desalination, chemical sensing and separation, and energy conversion and storage. [ 11–17 ] Pristine and chemically modified GOMs effectively block organic dyes and nanoparticles, [ 18 ] but fail to exclude smaller ions with hydrated diameters less than 9 Å.…”

Nature not only carefully prepares ingenious raw materials but also continuously inspires and guides human beings to create a wide variety of intelligent materials. As the most abundant mineral resource on earth, clay minerals are no longer synonymous with ceramics and cements. Many natural clay minerals can be exfoliated into single-or few-layered nanosheets with exquisite physicochemical properties, which can be reassembled into functional membranes with a macroscopic controllable size and microscopic ordered structure. They are thus used in many fields including chemistry, biology, energy, and environmental science. Strategic design represents one of the key processes to enhance the value of clay minerals and broaden their applications. In this work, the three frequently used approaches of exfoliation are highlighted and the six routes of assembly including casting, dip-coating, spray coating, vacuum filtration, electrophoretic deposition, and 3D printing are compared. The corresponding principles and advantages are summarized. Representative applications of clay-based multifunctional membranes in protection, separation, responsiveness, flexible electronics, and energy conversion are presented. The challenges and future perspectives of the claybased multifunctional membranes are discussed.

“…The unique attributes of 2D‐NLMs summarized above have stimulated intense research with regards to their use for fundamental understanding of solvation‐involved nanoionics, particularly exploring their potential application for ion separation, energy storage and conversion, and membrane science and ionic devices (such as ion transistors). Given that these potential applications have been thoroughly reviewed in several recent reviews, here we focus on demonstrating how the features of 2D‐NLMs have made them possible as a unique experimental platform and have enabled new techniques to help understand the key scientific problems related to solvated ion transport under nanoconfinement, namely ion sieving, externally regulated ion transport, size‐dependent ion transport and nanoconfined ion storage mechanisms. A few of representative examples are selected below to demonstrate the unique capabilities and enormous potential of 2D‐NLMs for nanoionics research.…”

View full text Add to dashboard Cite

Nanoporous laminar membranes composed of multilayered 2D nanomaterials (2D‐NLMs) are increasingly being exploited as a unique material platform for understanding solvated ion transport under nanoconfinement and exploring novel nanoionics‐related applications, such as ion sieving, energy storage and harvesting, and in other new ionic devices. Here, the fundamentals of solvation‐involved nanoionics in terms of ionic interactions and their effect on ionic transport behaviors are discussed. This is followed by a summary of key requirements for materials that are being used for solvation‐involved nanoionics research, culminating in a demonstration of unique features of 2D‐NLMs. Selected examples of using 2D‐NLMs to address the key scientific problems related to nanoconfined ion transport and storage are then presented to demonstrate their enormous potential and capabilities for nanoionics research and applications. To conclude, a personal perspective on the challenges and opportunities in this emerging field is presented.
