Ice accumulation poses a series of severe issues in daily life. Inspired by the nature, superwettability surfaces have attracted great interests from fundamental research to anti-icing and ice-phobic applications. Here, recently published literature about the mechanism of ice prevention is reviewed, with a focus on the anti-icing and ice-phobic mechanisms, encompassing the behavior of condensate microdrops on the surface, wetting, ice nucleation, and freezing. Then, a detailed account of the innovative fabrication and fundamental research of anti-icing materials with special wettability is summarized with a focus on recent progresses including low-surface energy coatings and liquid-infused layered coatings. Finally, special attention is paid to a discussion about advantages and disadvantages of the technologies, as well as factors that affect the anti-icing and ice-phobic efficiency. Outlooks and the challenges for future development of the anti-icing and ice-phobic technology are presented and discussed.

Metal-organic frameworks (MOFs), a new class of crystalline porous materials, can be applied in many fields as adsorbents, supercapacitors, catalysts, and so on because of, among others, their superior properties of large surface area, tunable pore size, diverse structures. However, the low stability and selectivity of traditional MOFs indicate that they are not the best configuration for the applications outlined above. In this case, a type of composite made from an assembly of graphene-based materials and MOFs that exhibits the advantages of the parent materials has attracted widespread attention in recent years. This review provides an overview of the recent developments of MOF/graphene-based materials, focusing on their applications in gas separation/storage, water purification, chemical sensors, batteries, supercapacitors, and catalysts, as well as their preparation methods.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201804950. traditional method, they can be excellent alternatives of single MOFs to overcome the above-mentioned difficulties. [34][35][36][37][38] Graphene-based materials have recently introduced new possible applications because of their unique structure and low toxicity, as well as their excellent electronic, thermal, electrochemical, and mechanical properties. [39] More recently, many reports have confirmed that the introduction of graphene-based materials into other materials can lead to surprising improvements in electronic conductivity and stability. [38,40] Under these circumstances, it is reasonable to consider whether composites made from the assembly of graphene-based materials and MOFs possess extraordinary characteristics given that the parent materials have complementary properties. [40][41][42] Naturally, the idea of hybridizing graphene derivatives with MOFs materialized and soon attracted widespread attention. [43][44][45] According to recent research, composites of MOF/graphene-based materials can integrate the advantages and mitigate the shortcomings of the individual components perfectly, enabling the composites to possess improved stability, enhanced electrical conductivity, high selectivity, and template effects. [34,[46][47][48][49] With the combination of MOF and graphene-based materials, the unexpected interactions take place and bring unique performance in many applications. Thanks to the ionic groups and the aromatic sp 2 domains, graphene-based materials can not only function as structural nodes, but also participate in bonding interactions, which would be more active in MOFs. What's more, carboxylate and pyridine groups of graphene-based materials play important part in the assemble, which could enhance the coordination bonding and guide the growth of MOF, providing a more beneficial structure. These special interactions are unique in MOF/graphenebased materials, which indicates that this kind of materials deserve more attention. As concluded in Scheme 1, the addition of graphene-based material...

“…The [Ni(C 10 H 26 N 6 )] 2+ complex had two vacant sites that could coordinate with the carboxylic groups of the functionalized GO, forming a pillared nanostructure (i.e., MGF), as shown in Figure b. Besides the framework, this strategy could also be applicable to fabricate 3D hybrid nanostructures such as hydrogels and aerogels . For instance, Cu 2+ ‐m‐phenylenediamine (Cu 2+ ‐mPD) complex was used to crosslink the GO nanosheets by coordination interaction, leading to a Cu 2+ ‐mPD‐GO hydrogel (Figure c) .…”

nanobelts), 2D materials exhibit exceptional physical properties including large theoretical surface area, tunable electronic properties, high optical transparency, and excellent mechanical properties. [2] However, the strong re-stacking tendency of 2D materials caused by van der Waals interaction may result in serious loss of surface area, which inevitably weakens their unique properties. Besides, 2D materials always show intrinsic deficiencies for specific applications, despite the merits mentioned above. As a typical example, TMDs possess high theoretical specific capacities for lithium-ion storage but exhibit unsatisfied cyclability and rate capability in practice, because of their aggregation, low conductivity as well as huge volume expansion during lithium-ion insertion/extraction. [3] One effective way to solve these problems is to construct hybrid nanostructures based on 2D materials. [4][5][6][7][8] Hybrid nanostructures, as a class of composite materials, are composed of two or more nanostructured building blocks. [9,10] Hybrid nanostructures not only can energetically combine the intriguing merits and overwhelm the deficiencies of each building block, but also may generate new functions and properties. [3][4][5][6][7][8][11][12][13] These advantages make hybrid nanostructures based on 2D materials highly promising for practical applications with high performance. [14][15][16][17][18] Regarding the multicomponent composition of hybrid nanostructures, the interfacial interaction between the building blocks lays the foundation for structural and morphological stability, thereby influencing the functions and properties of the resulting hybrid nanostructures. [19][20][21][22] In this sense, the rational design and construction of reliable interfacial interaction for hybrid nanostructures are not only important for achieving improved performance, but also critical for understanding the fundamentals of structureproperty relationship.Generally, there are five types of interfacial interactions, i.e., covalent bond, coordination bond, hydrogen bond, π-π interaction, and electrostatic interaction. [19][20][21][22] Covalent bond and coordination bond are much stronger than the other three in terms of bond energy, so the former two are more favorable for constructing hybrid nanostructures with reliable interfacial interaction. [19] However, most 2D materials are chemically inert, which means the covalent modification is not suitable for them. Alternatively, there are coordination atoms in most of 2D materials and their derivatives, and hence coordination 2D materials have received tremendous scientific and engineering interest due to their remarkable properties and broad-ranging applications such as energy storage and conversion, catalysis, biomedicine, electronics, and so forth. To further enhance their performance and endow them with new functions, 2D materials are proposed to hybridize with other nanostructured building blocks, resulting in hybrid nanostructures with various morphologies and structures. The prop...
