“…With the extension of friction time, the Al content strikingly decreases to 5.25% on the TA‐Al films with ≈2.0 µm. On the contrast, the C/O ratio gradually increases to 1.61 as increasing friction time, which is close to the theoretical C/O ratio of 1.7 for TA . The varying thickness of MPNs films is a negative function of the aluminum content but a positive function of C/O ratio.…”

co-workers reported a one-step method to obtain the uniform tannic acid-Fe (TA-Fe) films (11.9 ± 1.2 nm) by changing the pH value of solution. [2] Similar to the assembly of TA-Fe films, 18 different metal ions have been selected to design and prepare MPNs multifunctional capsules. [3] Additionally, a large variety of superstructures based on the polyphenol surface functionalization have been obtained through cross-linking interaction. [4] Such studies show that a design based on coordination bond between polyphenols and various metal ions can provide a platform to prepare multifunctional materials. However, the requirements of synthesis of MPNs are a wet environment, [2] which restricts their widespread applications of monomers with no or poor solubility in solvents. [5] The development of a solvent-free method to prepare MPNs films with tunable properties is an urgent requirement. Mechanochemistry, a green and sustainable technology, [6] is now emerging as an environmentally friendly alternative to conventional solution-based approach in the fields of porous carbon materials, [7] organic reactions, [8] nanomaterials, [9] and metal-organic complexes. [10] Dai and co-workers synthesized The development of functional metal-phenolic networks (MPNs) films by a simple and green strategy on metallic plane substrates for surface modification is a big challenge. Herein, tribochemistry, as an effective and robust method to prepare MPNs films with versatile applications and controllable thickness (≈1.5 nm to 2.2 µm) by surface coordination complexation derived from tannic acid (TA) and metal oxides or ions (M) on plane substrates, is reported. The mechanism of the formation of TA-M films is investigated in detail, showing that films are constructed by two-layer structures. At the bottom of films, the chelation of TA active moieties and M is triggered by friction, facilitating the coating growth and reducing the friction coefficient.There is a downward trend in the concentration of M with the thickness of films increasing, which is attributed to the diffusion of metal ions. As a result, the dominant structure of films changes into the hydrogen bonding or π-π stacking interaction among oligomers derived from coupling of the TA active moieties. Such facile surface modification strategy can broaden in situ mechanochemical synthesis of functional layers and open a promising route for the design of patterning, antifouling, and controlled release coatings.

“…As mentioned above, the contorted monomers such as TTSBI and PIM are one of great candidate to provide relatively low chain packing and rigid polymer backbone, resulting in high free volume and microporosity [48,65]. In addition, Priamine including highly reactive amine groups and long aliphatic chains is a good example as a monomer to produce the hydrophobic membrane surface [78]. Furthermore, these could be also good ideas to obtain the hydrophobic surface by the use of fluoro-based materials as an additive [92,96] or a coating source [97] and the surface modification with hydrophobic materials [98].…”

“…Among them, tannic acid [76][77][78][79][80], quercetin [81], morin hydrate [82], cyclodextrin [83][84][85], chitosan [86], and vanillin [87] played a well role as a reactive material, resulting in the formation of the stable selective layer having great performance. However, most of approaches have changed only one monomer.…”

Thin-Film Composite Nanofiltration Membranes for Non-Polar Solvents

et al. 2021

Organic solvent nanofiltration (OSN) has been recognized as an eco-friendly separation system owing to its excellent cost and energy saving efficiency, easy scale-up in the narrow area and mild operation conditions. Membrane properties are the key part in terms of determining the separation efficiency in the OSN system. In this review paper, the recently reported OSN thin-film composite (TFC) membranes were investigated to understand insight of membrane materials and performance. Especially, we highlighted the representative study concepts and materials of the selective layer of OSN TFC membranes for non-polar solvents. The proper choice of monomers and additives for the selective layer forms much more interconnected voids and the enhanced microporosity, which can improve membrane performance of the OSN TFC membrane with reducing the transport resistance. Therefore, this review paper could be an important bridge to connect with the next-generation OSN TFC membranes for non-polar solvents.

“…MPN‐beschichtete Polyethersulfon‐Membranen zeigten hohe Wasserdurchflüsse und “Antifouling”‐Eigenschaften gegenüber Proteinen und Zellen und demonstrieren damit Anwendungspotenzial in der Wasseraufbereitung. Aufgrund der hohen Bindungsaffinität von Catechol zu Metallen könnten Catechol‐beschichtete Substrate auch bei der Umweltsanierung zur Entfernung von Schwermetallen (Abbildung h) und organischen Verunreinigungen eingesetzt werden . Darüber hinaus könnten extrem dünne Filme mit eingebetteten PDA‐modifizierten Nanopartikeln zur CO 2 ‐Abtrennung verwendet werden …”

Phenolische Bausteine für die Assemblierung von Funktionsmaterialien

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.
