Special Issue Information

Dear Colleagues,

Metal corrosion remains a critical industrial challenge, with traditional anticorrosive coatings failing in harsh environments due to poor weather resistance and barrier properties. Since the rise of nanotechnology, nanocomposite anticorrosive coatings incorporating nanoparticles such as BN, graphene, and TiO2 have emerged, shifting research from an early focus on nanoparticle dispersion and interfacial compatibility to multiscale synergistic mechanisms and, recently, force-thermal-chemical coupling failure mechanisms under multifactor environments. Yet, challenges persist in optimizing "function-structure-service behavior" integration for high-end equipment protection.

This Special Issue of Nanomaterials focuses on fundamental research, technological innovation, and engineering applications of nanostructured anticorrosive coatings. It seeks papers on nanomaterial design/modification, coating preparation/process optimization, performance characterization/failure mechanisms, service behavior/environmental effects, and engineering applications. Hot topics include synergistic reinforcement of 2D material-based coatings, smart self-healing/superhydrophobic coatings, multiscale failure modeling via machine learning, and green nanocoating technologies like waterborne systems and biomass-based materials.

We kindly encourage you to submit a manuscript regarding one of the above topics to this Special Issue. We look forward to receiving your contributions exploring innovative solutions and advancing nanocoating technologies for critical industrial applications.

Corrosion in harsh environments causes global economic losses exceeding 3 trillion US dollars annually. Traditional silicone epoxy (SE) coatings are prone to failure due to insufficient physical barrier properties and lack of active protection. In this study, cerium dioxide (CeO2) was in situ grown on the surface of hexagonal boron nitride (h-BN) mediated by polydopamine (PDA) to prepare BN-PDA-CeO2 ternary nanocomposites, which were then incorporated into SE coatings to construct a multi-scale synergistic corrosion protection system. Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and transmission electron microscopy (TEM) confirmed the successful preparation of the composites, where PDA inhibited the agglomeration of h-BN and CeO2 was uniformly loaded. Electrochemical tests showed that the corrosion inhibition efficiency of the extract of this composite for 2024 aluminum alloy reached 99.96%. After immersing the composite coating in 3.5 wt% NaCl solution for 120 days, the coating resistance (Rc) and charge transfer resistance (Rct) reached 8.5 × 109 Ω·cm2 and 1.2 × 1010 Ω·cm2, respectively, which were much higher than those of pure SE coatings and coatings filled with single/binary fillers. Density functional theory (DFT) calculations revealed the synergistic mechanisms: PDA enhanced interfacial dispersion (adsorption energy of −0.58 eV), CeO2 captured Cl (adsorption energy of −4.22 eV), and Ce3+ formed a passive film. This study provides key technical and theoretical support for the design of long-term corrosion protection coatings in harsh environments such as marine and petrochemical industries. Full article
