MXene has excellent anticorrosion and self-lubricating properties. It is widely used in the field of anticorrosion and wear resistance. However, there is a strong interaction between MXene nanosheets, which makes it easy for them to agglomerate in the coating and affects the mechanical properties of the coating. Thus, the application of MXene is limited. In this study, MXene is modified by 2,5-diaminobenzenesulfonic acid, which can reduce the aggregation of MXene in the coating. MXene is functionalized by using tetrabutylphosphorus hydroxide benzotriazole lignin composite material (BTA-P4444-Lig) with environmental protection, anticorrosion, and lubricating properties. The prepared MXene has excellent anticorrosion and lubrication properties. Functionalized MXene (f-MXene-P) is used as a filler for environmentally friendly waterborne epoxy (WEP) coatings. Electrochemical tests show that the impedance of f-MXene-P/WEP (3.91 × 107 Ω·cm2) is an order of magnitude higher than that of WEP (1.89 × 106 Ω·cm2). The maze effect of MXene and the protective film formed by BTA-P4444-Lig on the surface of Q235 steel synergistically enhance the anticorrosion performance of f-MXene-P/WEP. The friction test results show that the friction coefficient of f-MXene-P/WEP (0.068) is much lower than that of WEP (0.612). The synergistic effect of MXene and BTA-P4444-Lig with lubricating properties improves the wear resistance of f-MXene-P/WEP.

A three-dimensional hollow NiCo 2 O 4 structure was successfully prepared with a precipitation-hydrothermal method. A balance between magnetic and dielectric losses was achieved by using a hollow NiCo 2 O 4 structure loaded with benzotriazole (BTA), and thus the performance of electromagnetic waves was attenuated. The minimum reflection loss value of BTA@NiCo 2 O 4 at 16.01 GHz was −35.39 dB when the absorber thickness was 2 mm, at which the absorption bandwidth for an RL of less than −10 dB is as high as 4.64 GHz. The absorption mechanism was characterized by the synergy among interfacial polarization, multiple reflection, and dipole polarization enhancement between NiCo 2 O 4 and BTA . Interestingly, the epoxy/BTA@NiCo 2 O 4 coating not only exhibited an outstanding microwave absorption (MA) performance but also has excellent anticorrosion and self-healing properties, as shown by the results of electrochemical impedance spectroscopy and confocal laser scanning microscopy. This work would be very helpful to the development of novel coatings with excellent MA performance and anticorrosion and self-healing properties.

Post-chemical mechanical polishing (CMP) cleaning is an indispensable process to remove organic residues and particles on the wafer surface after CMP. Benzotriazole (BTA), a dominant corrosion inhibitor in Cu-CMP slurry, can easily remain on the copper surface after CMP, affecting the performance and yield of devices, and its removal has attracted more attention. This paper revealed the effect and mechanism of three amino acids, lysine, serine, and proline, on BTA removal in tetraethyl ammonium hydroxide-based alkaline solutions during post-Cu-CMP cleaning. Experimental results showed a diminishing enhancement in the cleaning efficiency of BTA after adding lysine (97.1%), serine (96.7%), and proline (94.1%) with almost the same concentration. Ultraviolet–visible absorption spectrum proved the lysine’s complexing ability was slightly better than the other. Besides, quantum chemical parameters of amino acid molecules calculated by density functional theory further suggested that lysine has more reactive sites and mainly bonds with copper through N2 and N8. The adsorption structures of three amino acids were simulated through the molecular dynamics method, and lysine turned out to be parallel absorbed on the Cu (1 1 1) surface with the lowest adsorption energy of −30.24 eV. Finally, the cleaning process simulation revealed the dynamic behaviors of BTA and lysine.

MIL-88(Fe) was used as an oxidant and a hard template for the synthesis of polypyrrole (PPy) on its surface, and the formation of PPy made the surface of MIL-88(Fe) rougher as well as more voids formed in the interior. The increased specific surface area allowed more benzotriazole (BTA) (17.8 wt%) loaded on PPy/MIL-88 particles. BTA/PPy/MIL-88(Fe) was employed as a novel corrosion inhibitor to enhance the corrosion resistance of epoxy coating for carbon steel. BTA/PPy/MIL-88(Fe) filler improved the corrosion resistance of EP coating without/with artificial scratch by delaying the cathodic and anodic reactions in corrosive media. Both BTA and MIL-88(Fe) played the role of corrosion inhibitors, making EP coating possess active corrosion protection and pH-sensitive performance. Besides, BTA/PPy/MIL-88(Fe) enhanced the adhesion of EP coating by filling the pores inside.

To fulfill practical demands for metal protection, a more in-depth exploration of the corrosion resistance of cerium dioxide nanoparticles (CeO 2 NPs) is essential. In this work, biomimetic porous CeO 2 NPs, featuring a high concentration of oxygen vacancies , were synthesized using a sol-gel method. Biomimetic porous CeO 2 NPs, characterized by the presence of oxygen vacancies , served as nanocontainers for benzotriazole (BTA) loading. Following this, TEOS-BTA@CeO 2 NPs were prepared by introducing tetraethyl orthosilicate (TEOS), a TEOS film encapsulating BTA@CeO 2 . Through electrochemical and salt spray testing, the 3 % TEOS-BTA@CeO 2 coating demonstrated superior corrosion resistance for the substrate when compared to both the 3 % CeO 2 coating and the 3 % BTA@CeO 2 coating. Throughout the entire corrosion process, the intelligent release of BTA facilitated by the TEOS film, coupled with the reduction in corrosion current due to oxygen vacancies serving as electron-capturing centers in cerium oxide, further enhances the corrosion resistance of CeO 2 NPs. This work marks a significant advancement in the exploration of nanocomposites for the practical utilization of CeO 2 NPs in combating metal corrosion.

As novel solvents, deep eutectic solvents (DESs) are non-toxic, easily producible and biocompatible, which is attractive for eutectogel fabrication. In this work, a benzene 1,3,5-tricarboxamide (BTA) derivative (substituted by three hexanoic acid) was selected to prepare a supramolecular gel in a suitable DES composed of choline chloride and phenylacetic acid molecules. The obtained eutectogel exhibited higher stability than that produced in conventional solvents. The gel microstructure was composed of spiral fiber networks as confirmed from atomic force microscopy and scanning electron microscopy observations. Macroscopic chirality was therefore recognized by the circular dichromatic spectrum, though such a supramolecular chiral signal was random. To explore the gelation mechanism, the effect of BTA derivative molecular structure change was systematically investigated. With the help of Fourier transform infrared spectroscopy and powder X-ray diffraction, the gel formation was attributed to the π–π stacking of adjacent BTA molecules and the three-fold hydrogen bond between amide groups or the hydrogen bond between carboxylic groups. Furthermore, the directional hydrogen bonds between BTA and solvent molecules induced their aggregate to form one-dimensional fibers, which were either left- or right-handed. The obtained results not only extend the gel systems in DESs, but also help design the supramolecular chirality from non-chiral molecules.

Integration of both passive and active corrosion-protecting mechanisms is an effective method for endowing sol-gel derived coatings with long-term anticorrosion performance. To provide “smart” functionality for sol-gel coating, a novel self-healing nanocontainer is fabricated via the in-situ growth of 1H-benzotriazole-inbuilt zeolitic imidazolate framework (BTA-ZIF-8) on hydroxylated hexagonal boron nitride nanosheets (BN-OH), which exhibits efficient pH-dependent inhibitor release behavior at both acidic and alkaline media. Electrochemical measurements reveal that sol-gel coating containing the BTA-ZIF-8@BN-OH nanocontainers exhibits superior anticorrosion performance and long-term corrosion protective capability, with |Z| 0.01Hz increased by nearly three orders of magnitude (∼2 × 10 8 Ω·cm 2 ) compared to that of pure sol-gel coating after 28 days of saline solution immersion. In addition, the EIS measurements on sol-gel coating surfaces with artificial scratches show increased impedance values after prolonged immersion in saline solution, indicative of effective active inhibiting effect. This phenomenon is the result of the synergistic effect of both passive and active corrosion protection . The active protection (inhibiting effect) is provided by the on-demand release of inbuilt BTA inhibitor from ZIF-8 frameworks, whereas the passive protection (barrier performance) is achieved through the “labyrinth effect” of BN-OH nanosheets as well as the improved interfacial compatibility of nanocontainers with surrounding sol-gel matrix by surface hydroxylation of h-BN nanosheets. This nanocontainer design offers a facile strategy for fabricating self-healing sol-gel coatings with the exceptional anticorrosion properties.

In this work, the carbon-based 2D-3D composite nanocontainers endowing coatings with both active and passive protection properties were constructed by the sp 2 /sp 3 hybridized carbon as a versatile strategy. The classic graphene oxide (GO, sp 2 C) and Covalent Organic Framework-300 (COF-300, sp 3 C) were chosen as examples and benzotriazole (BTA) as the inhibitor to fabricate the GO/COF-300@BTA nanocontainer. The composite nanocontainers embedded in polyvinyl butyral (PVB) coatings were applied on cupper substrates to get mechanical enhancement, active and passive corrosion protection performance. The tensile strength of GO/COF-300/PVB (12.38 Mpa) was two times higher than that pure PVB (5.96 MPa). The active protection performance was ensured by the corrosion inhibitors encapsulated in the 3D porous carbon skeleton. The passive protection performance was endowed by the maze effect of the 2D carbon-based nanosheets. The |Z| 0.01 Hz of Cu/(GO/COF-300@BTA)/PVB was higher than 10 9 Ω·cm 2 , which was two magnitudes larger than that of PVB coating, demonstrating the anti-corrosion properties. In addition, the quantum chemical calculation and molecular dynamics simulation results elaborated the adsorption states of BTA on copper substrate and the compatibility between the molecular chains of the PVB and the GO/COF-300 nanocontainer.

Benzotriazole-loaded polydopamine/polyaniline (BTA@PDA/PANI) microcapsules are prepared vis the combination of a hard template method and in-situ polymerization. The PDA/PANI hollow microspheres are first prepared using SiO 2 as a hard template and etching them with hydrofluoric acid . The BTA corrosion inhibitor is then loaded into the PDA/PANI hollow microspheres to obtain the BTA@PDA/PANI microcapsules. The mean particle size and shell thickness of the synthesized microcapsules are 8.3 and 2.1 µm, respectively. The load capacity of BTA is above 20 wt%. The corrosion resistance of epoxy coatings with different contents and types of microcapsules is compared by saline immersion and electrochemical impedance tests. A scratched coating with 1 wt% BTA@PDA/PANI microcapsules has the best anti-corrosion effect. The synergistic anticorrosion mechanism of BTA, PDA and PANI is revealed and confirmed.

Deep tissue infections caused by pathogenic bacteria seriously threat the lives of patients. In this study, a smart heterostructured Au/Cu–BTA (BTA = 1,2,4,5-benzenetetramine) with microwave (MW) response is synthesized via NaBH 4 reduction of HAuCl 4 on the Cu–BTA. Au/Cu–BTA exhibits excellent hyperthermy and dynamics under MW irradiation. The MW thermal mechanism of Au/Cu–BTA is attributed to the excellent dielectric loss and polarization of the heterogeneous interface. Meanwhile, the surface energy levels of the Cu–BTA interface alleviate the difficulty of electron hopping through multistage transition. Therefore, MW can excite Cu–BTA to produce free electrons. Subsequently, Au nanoparticles rapidly increase electron transfer and inhibit electron–hole recombination. Hence, the yields of reactive oxygen species can be enhanced for MW dynamic therapy. Consequently, under 10 min of MW irradiation, Au/Cu–BTA killed 99.998% ± 0.001% of Gram-positive Staphylococcus aureus , 99.966% ± 0.014% of methicillin-resistant Staphylococcus aureus , and 96.871% ± 0.831% of Gram-negative Pseudomonas aeruginosa . The effective MW bacteria-killing strategy designed in this study shows significant potential for application in the MW-responsive treatment of deep tissue infections without antibiotics.

The spatial distribution of functional nanofillers in anticorrosion coatings significantly influences their ability to seal micropores/cracks and enhance self-healing properties. In this study, a novel dual-responsive nanocontainer loaded with the corrosion inhibitor benzotriazole (BTA) was developed for active corrosion protection in waterborne epoxy coatings. The magnetic nanocontainers (Fe 3 O 4 @BTA-ZIF-8) were synthesized via the in-situ growth of BTA-encapsulated zeolitic imidazolate frameworks-8 (ZIF-8) on the surface of anion-modified Fe 3 O 4 nanoparticles. This unique structure endows the nanocontainers with pH responsiveness for controlled BTA release under corrosive conditions. Additionally, under an external magnetic field, the nanocontainers migrate toward the coating/metal interface, increasing the local inhibitor concentration and improving corrosion resistance. Potentiodynamic polarization tests revealed that the nanocontainers achieved an inhibition efficiency of 82.40 % on carbon steel surface after 24 h of saline immersion. Cross-sectional analysis of the composite coatings confirmed the magnetic-field-induced accumulation of nanocontainers at the coating/substrate interface, facilitating rapid and efficient inhibitor release. Electrochemical impedance spectroscopy results further revealed a low frequency impedance value (|Z| 0.01 Hz ) of 1.42 × 10 10 Ω·cm 2 for epoxy coating containing magnetically distributed Fe 3 O 4 @BTA-ZIF-8 nanocontainers after 35 d of saline immersion, over an order of magnitude higher than that of coating without magnetic modulation. Furthermore, the scratched composite coating after magnetic modulation exhibited an improvement efficiency (η) of 165.04 % after 6 h of immersion, compared to only 22.76 % for the non-modulated counterpart. These results confirm the long-term protective performance of Fe 3 O 4 @BTA-ZIF-8 within epoxy coatings under magnetic modulation. This study is the first to introduce a magnetic MOF-based nanomaterial for corrosion protection, demonstrating the potential of epoxy coatings with magnetically directed distribution and pH-responsive inhibitor release.
