Polyphenolic molecules have become attractive building blocks for bioinspired materials due to their adhesive characteristics, capacity to complex ions, redox chemistry, and biocompatibility. For the formation of tannic acid (TA) surface modifications based on silicate-phenolic networks, a high ionic strength is required. In this study, we investigated the effects of NaCl, KCl, and LiCl on the formation of TA coatings and compared it to the coating formation of pyrogallol (PG) using a quartz…

Silicic Acid-Mediated Formation of Tannic Acid Nanocoatings.
The results indicate the specific importance of orthosilicic acid in the coating formation of polyphenolic molecules with multiple ortho-dihydroxy groups and open new possibilities to deposit TA on interfaces.
Influence of Ionic Strength on the Deposition of Metal-Phenolic Networks.
The influence of ionic strength (0-2 M NaCl) on the conformation ofMPN precursors in solution and how this determines the final thickness and morphology of MPN films is explored.
Salt-Induced, Continuous Deposition of Supramolecular Iron(III)-Tannic Acid Complex.
It is suggested that the positively charged cations screened the negative surface charges of Fe3+-TA complex particles, leading to coagulation and continuous deposition, further supported by the ζ-potential measurement and time-resolved dynamic light-scattering analysis.
Complexation of Condensed Tannins with Metal Ions
The ortho-dihydroxyl group on the flavonoid B-ring of condensed tannins is the main group involved in metal complexation. Potentimetric and spectrophotometric studies have shown that iron(III) forms
Silicate‐Phenolic Networks: Coordination‐Mediated Deposition of Bioinspired Tannic Acid Coatings
By using QCM‐D it is demonstrated the advantages of Siaq, compared to using transition‐metal ions, to improve the coating efficiency under mildly acidic conditions and broadens the use of TA for surface modifications in technological and biomedical applications.
Deposition Kinetics of Bioinspired Phenolic Coatings on Titanium Surfaces.
Coating evaluation by ellipsometry and AFM confirmed the deposition kinetics determined by QCM-D and revealed maximum coating thicknesses of approximately 50 and 75 nm for TA and PG, respectively.
Mechanism of in situ surface polymerization of gallic acid in an environmental-inspired preparation of carboxylated core-shell magnetite nanoparticles.
The present work explores the mechanism of polymerization with the help of potentiometric acid-base titration, dynamic light scattering, UV-vis,UV-visible light spectroscopy, FTIR-ATR, and XPS techniques, which revealed that, prior to polymerization, the GA monomers became oxidized to poly(carboxylic acid)s due to ring opening while Fe(3+) ions reduced to Fe(2+).
The Chemistry behind Catechol-Based Adhesion.
The aim of this Review is to present recent investigations that elucidate the origin of the strong and versatile adsorption capacities of the catechol moiety and the effects of extrinsic factors that play important roles in the overall adhesion process, such as pH value, solvent, and the presence of metal ions.
