“…Metallic mesh, cotton fabrics and textile membranes stand for the most studied superwetting materials by the surface modification. Furthermore, novel porous material-based superwetting materials, such as metal organic frameworks (MOFs), graphene, carbon nanotube, hydrogel and covalent organic frameworks (COFs), have also been proposed as an efficient separation strategy [16][17][18][19][20]. These smart material-based membrane techniques have received high research interest for the efficient separation processes with the characteristics of low energy consumption and simple separation devices.…”

There is an urgent need to develop new and improved oil-water separation materials with high stability and reusability for the cleanup of oily environmental pollutants. Here, fluorinated poly(ionic liquid)s were synthesized and their structure and property were characterized by nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy and thermogravimetric analysis. These fluorinated poly(ionic liquid)s were proposed as superhydrophobic coating on different metallic substrates through the combination of tethering fluorine groups in the PIL’s cation and anion exchange, and the superhydrophobic coating showed compactly stacked morphology under scanning electron microscope. The results of surface wettability experiments indicated that nearly all the fabricated materials showed a water contact angle larger than 150°, which is devoted to superhydrophobic nature. Moreover, for longer alkyl chain ILs and materials with smaller pore sizes, the water contact angle can be increased. At the same time, the fabricated superhydrophobic material exhibits a relatively high oil phase permeate flux, benefiting from the loose fibrous structure. Take the PIL@SSM300 for instance, the permeate fluxes were reached as high as 374,370 L·m−2·h−1, 337,200 L·m−2·h−1 and 302,013 L·m−2·h−1 for petroleum ether, hexane and cyclohexane, respectively. Instead, water is effectively repelled from the superhydrophobic surface. These virtues make the fabricated superhydrophobic material an effective membrane for oil/water separation under gravity. The separation efficiency and water contact angle are nearly unaffected after at least 20 cycles, confirming the excellent robustness of the coatings. These efficient poly(ionic liquid)s-based superhydrophobic materials possessed the potential to be used for oil/water separation.

“…In terms of global concerns, crude oil spills constitute a major problem. There is a lot of promise in the superparamagnetic γ-Fe2O3/ZIF-7 composite for removing crude oil and other hydrocarbon ( such as acetone and toluene) contaminants from water [63]. It is possible to separate oil (dichloromethane, ether, dodecane, gasoline) from water using the UiO-66-NH2/chitosan composite membrane, even under extreme conditions [64].…”

Metal Organic Frameworks (MOFs) are expected to become a major player in different industrial sector as a result of biological performance, photocatalysis, adsorption and absorption behavior, capacitance, improved anodic performance in energy storage. In biomedical industries, MOFs utilize antimicrobial characteristics and biosensing, bioimaging, therapeutic, drug delivery capabilities. MOF can be used as a food safety and food packaging agent since they prevent microbes. By photocatalysis MOF can contribute to wastewater treatment. MOFs adsorption and absorption characteristics can remediate groundwater. Improved capacitance and anodic behavior of MOF will contribute to energy storage device improvement. MOFs are also capable of separating gases from mixtures. Thus, MOF will play vital role in biomedical, food, water-treatment industry, oil-gas industry, and energy storage industry. Energy, environment, biomedical applications make MOF important in 4 th industrial revolution. This study will focus on special properties along with different industrial application and show the effectiveness of MOF in 4 th industrial application.

In recent years, there has been considerable focus on the development of charge transfer (CT) complex formation as a means to modify the band gaps of organic materials. In particular, CT complexes alternate layers of aromatic molecules with donor (D) and acceptor (A) properties to provide inherent electrical conductivity. In particular, the synthetic porous frameworks as attractive D–A components have been extensively studied in recent years in comparison to existing D–A materials. Therefore, in this work, the synthetic porous frameworks are classified into conjugated microporous polymers (CMPs), covalent organic frameworks (COFs), and metal–organic frameworks (MOFs) and compare high‐quality materials for CT in semiconductors. This work updates the overview of the above porous frameworks for CT, starting with their early history regarding their semiconductor applications, and lists CT concepts and selected key developments in their CT complexes and CT composites. In addition, the network formation methods and their functionalization are discussed to provide access to a variety of potential applications. Furthermore, several theoretical investigations, efficiency improvement techniques, and a discussion of the electrical conductivity of the porous frameworks are also highlighted. Finally, a perspective of synthetic porous framework studies on CT performance is provided along with some comparisons.
