“…Polydopamine containing amino, hydroxy, and benzene rings connected MgAl-LDH and poly(methyl vinyl ether-alt-maleic anhydride) by mussel-inspired chemistry and a ring-opening reaction. The absorption capacity of this ternary absorbent is twice that of the pristine MgAl-LDH [86]. Polydopamine also can connect α-amino phosphonate chains and MgAl-LDH by a combinatorial procedure of mussel-inspired chemistry and Kabachnik-Fields [87].…”

“…After adsorbing heavy metal ions, LDH has a poor ability to recycle and reuse, especially by isomorphous substitution to adsorb heavy metal ions. As shown in Figure 12b, after four cycles, the absorption efficiency of pristine LDH is less than 10%, while the absorption efficiency of functionalized LDH is more than 80% [86]. The current research focuses on the absorption capacity after each cycle and rarely discusses the reason for the decline in absorption capacity during the cycle.…”

The use of functional material can help mitigate the pollution by heavy metals, which presents an array of risks to human production and life. This work provides a comprehensive review of the current knowledge on functionalized layered double hydroxide (LDH) as a heavy metal absorption material, by synthesizing the information from a total of 141 relevant publications published since 2005. LDH provides a potentially highly efficient method to adsorb heavy metal ions, which is simple to prepare and of low cost. The lack of functional groups and structural components of pristine LDH, however, limits the absorption capacity and widespread applications of LDH. Through intercalation, surface modification, or loading on substrates, functional groups or structural components are introduced into the pristine LDH to prepare functionalized LDH. In this process, the hydroxyl group and the valence state of [Mg(OH)6] octahedrons play a crucial role. Functionalized LDH can be endowed with selective absorption capacity and enhanced stability and recyclability. After adsorbing heavy metal ions, functionalized LDH can be readily separated from the liquid phase. These aspects are discussed, along with the structure and composition, shape and size, and synthesis methods and research tools of LDH. This work concludes with the discussion of preparation and utilization and a look to the future in terms of identified research needs regarding the preparation, use, and recycling (or upcycling) of economical and environmental-friendly LDH.

Over the past five years, a lot of research activities in polymer composites were done in order to improve environmental sustainability and to present advantages for commercial applications of water treatment and desalination. Polymers offered tunable properties, improved processability, remarkable stability, high surface area for fast decontamination, selectivity to eliminate different pollutants, and cost-cutting of water treatment. Hence, the development of polymeric materials is one of the future directions to meet the environmental water standards and to supply the water requirements of the growing populations. This review highlighted the very recent achievements in fabrication, characterization, and applications of polymeric composites used for water treatment and desalination. The polymeric modifications, the addition of functional groups, and the assemblies of nanomaterials were also discussed in detail. In particular, great attention was paid to the recent advances in polymer/polymer composites, polymer/carbon composites, and polymer/clay composites, presenting their usage in the removal of various types of contaminants, e.g., metal ions, dyes, and other toxic pollutants. The review also summarized the main advantages and disadvantages of the different adsorbent materials. Specific attention was paid to the mechanism of adsorption, including chemisorption and physisorption mechanisms. In addition, the challenges and the future perspectives were identified to reach the optimal performance of the different adsorbents.

“…Pristine C 60 displayed overwhelmingly high thermal-stability with a mass residual ratio of 95.9 wt% when the temperature was continuously raised to 700 • C. After surface modification of PDA, no significant thermal decomposition was observed in view of the complicated composition of PDA, and the mass residue of C 60 -PDA was reduced to 69.4 wt%. The increased weight loss could be ascribed to the combustion of the adhesive PDA, since the pure PDA was reported to completely decompose at up to 600 • C [51]. When GSH was introduced into C 60 -PDA by the aid of Michael addition reaction, the residue in C 60 -PDA-GSH was much less in comparison with C 60 and C 60 -PDA.…”

Rational design and modification of the all-carbon fullerene cages to meliorate their nature of hydrophobicity is critical for biomedical applications. The outstanding electron affinity of fullerenes enables them to effectively eliminate reactive oxygen species (ROS), the excess of which may lead to health hazards or biological dysfunction. Herein reported is a facile, mild, and green approach to synthesizing the favorable water-soluble C60 nanoparticles capable of ROS-scavenging by combining the mussel-inspired chemistry with the Michael addition reaction. Various characterization techniques, including Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectra (XPS), thermogravimetric analysis (TGA), transmission electron cryomicroscopy (Cryo-TEM), and dynamic laser scattering (DLS) were carried out to confirm the satisfactory preparation of the hybrid C60-PDA-GSH nanoparticles, which exhibited apparent scavenging capacity of DPPH and hydroxyl radicals in vitro. Additionally, the biocompatible C60-PDA-GSH nanoparticles entered into cells and displayed a universal cytoprotective effect against oxidative press induced by H2O2 in four kinds of human cells at a low concentration of 2 μg/mL. The ease and versatility of the strategy present in this work will not only trigger more fullerene-based materials by the immobilization of diverse functional molecules, but will also extend their possible applications.
