“…The dopamine chemistry mediated SI‐ATRP on the MF sponge was evaluated through the free PDMS brush generated by sacrificial coinitiator . As displayed in Figure S3 of the Supporting Information, the chemical structures of monomethacryloxypropyl‐terminated PMDS (MA‐PDMS) monomer and PDMS brush were firstly identified by 1 H NMR spectra.…”

Developing sponge materials integrating excellent flame retardancy, multitasking separation performance, and efficient emulsion-breaking ability is significant but challenging for the remediation of oil spills causing fires and environmental damages. Herein, a superhydrophobic oil-water separation sponge material, containing a melamine-formaldehyde (MF) sponge substrate, magnetic polydopamine (PDA) coating, and branched polydimethylsiloxane (PDMS) brush, through dopamine-mediated surface initiated atom transfer radical polymerization (SI-ATRP) is fabricated. The synergistic flame resistance of the MF substrate and PDMS brush significantly improves its adaptability in fire. More importantly, the decorated PDMS brushes can effectively overcome the size mismatch between sponge macropores and tiny emulsified droplets, while remaining the intrinsic macroporous characteristic. When treating W/O emulsions, the PDMS brushes stretch up to act as "interface-breaking blades" to accelerate the coalescence of emulsified water droplets. Meanwhile, such PDMS brushes can serve as "oil-trapping tentacles" to efficiently capture oil droplets when treating O/W emulsions. Such material design synergistically contributes to satisfactory separation efficiency (98.7%) and ultrahigh permeation flux (up to 1.35 × 10 5 L m −2 h −1 ), even for treating high viscosity emulsions. Besides, the reported sponge also inherits robust durability, superior recyclability, and convenient magnetic collection. These features make the sponge promising for multitasking and highly efficient oil-water separation.

“…Our group also developed an adhesive based on dynamic covalent chemistry of phenylboronic acids (PBA) and catechols . Catechols, similar to other 1,2 and 1,3‐diols, bind reversibly to boronic acids wherein the equilibrium constant is determined by factors as the pk a of the PBA, the geometry of the diol or the pH of the solution.…”

Responsive interfaces are interfaces that show a defined and reversible change in physical properties in response to external stimuli. Typically, responsive interfaces result from the immobilization of responsive molecular components at the interface that translate a nanoscale signal into a macroscopic effect. Responsive interfaces can also be obtained if the topology of the interface can be reversibly changed using an external stimulus. As the surface of any material is its connection to the environment, responsive interfaces provide opportunities for interactive materials which are not only able to change properties upon demand, but also sense their environment and act autonomously. The application of responsive molecular components at interfaces, however, requires chemical and physical compatibility with the material surface of interest, posing a challenge not least in the retention of the responsive functionality. The state of the art in "active" interfaces which display responsive wettability, permeability, or adhesion is discussed, with a particular emphasis on microscale and nanoscale patterning since patterned interfaces can give rise to unique material properties. Finally, perspectives in the development of responsive interfaces, as well as promising approaches for bypassing the most prominent challenges are discussed.

Phenolische Materialien sind seit langem für ihre Verwendung in Farbtinten, in Holzbeschichtungen und zur Ledergerbung bekannt. In letzter Zeit ist jedoch ein wachsendes Interesse an der Entwicklung moderner Werkstoffe aus phenolischen Bausteinen zu verzeichnen. Die intrinsischen Eigenschaften von phenolischen Verbindungen, wie Metallchelat‐Bildung, Wasserstoffbrücken, pH‐Ansprechverhalten, Redoxpotentiale, Radikalfänger, Polymerisation und Lichtabsorption, haben sie zu einer eigenständigen Klasse von Strukturelementen für die Synthese von funktionellen Materialien gemacht. Aus Phenolverbindungen hergestellte Materialien behalten viele ihrer nützlichen Eigenschaften, oft mit synergistischen Effekten bei Anwendungen, die von der Katalyse bis zur Biomedizin reichen. Dieser Aufsatz gibt einen Überblick über die verschiedenen funktionellen Materialien, die aus natürlichen und synthetischen phenolischen Bausteinen hergestellt werden können, und über ihre Anwendungen.
