Corrosion and biological fouling present notable challenges for the growth of the marine industry. Since medetomidine (MM) has been shown to induce hyperactivity and interfere with barnacle larvae settlement, we synthesized MM and its analogues, 4-(1-(3,4-dimethyl phenyl)ethyl)-1H-imidazole (MM-2), 5-(1-phenylethyl)-1H-imidazole (MM-3) and 4-(1-(3,4-dichlorophenyl)ethyl)-1H-imidazole (MM-4), to explore their antifouling effectiveness in marine settings. The anticorrosive epoxy resin (EP) was integrated with these antifouling medetomidines to develop coatings that offer both antifouling and anticorrosion benefits. Among the compounds assessed, dichlorosubstituted medetomidine analogue (MM-4) stood out as the most performing candidate. Compared to EP/MM, the inhibition rates of EP/MM-4 against Escherichia coli and Staphylococcus aureus increased by 24.69 % and 39.28 %, respectively. Moreover, EP/MM-4 showed impressive activities against marine bacteria Vibrio fescheri and Cyclotella cryptica, with 91.93 % and 91.21 % inhibition rates, while maintaining stability in the coating by the fourth day. Notably, the EP/MM-4 coating not only offers effective antibacterial and algal resistance, but also help prevents large organisms from deposition in seawater for up to 90 d. The impedance value of MM-4 remains at 6500 Ω·cm², demonstrating excellent anticorrosion performance, with a continuous anticorrosion efficiency of 97.21 % for 24 h. This research holds great promise for practical application in marine and industrial facilities has broad prospects.

Water-induced degradation threatens sandstone cultural relics, highlighting the need for effective protection. This study applies a nano-coating of PFDTS-modified TiO₂/SiO₂ to sandstone, optimizing PFDTS concentration, coating penetration depth, and hydrophobicity. A TiO₂-to-SiO₂ ratio of 75:25 with 80 μL of PFDTS achieved high water and oil contact angles of 152.7° and 145.7°, respectively. After 210 h of UV exposure, contact angles showed minimal reduction, confirming the coating's durability. Additionally, air permeability is preserved to maintain sandstone breathability. These findings provide valuable insights for safeguarding sandstone heritage sites against weathering.

This study introduced new anticorrosive pigments by modigying attapulgite (ATP) via a silane coupling agent. An organic corrosion inhibitor, 2-mercaptobenzothiazole (MBT) was loaded on the surface of modified-ATP. The morphologies and compositional structures of ATP@MBT were characterized utilizing Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). UV–vis spectroscopy was used to study the loading and release behavior of MBT. ATP@MBT was incorporated into a polyurethane coating and the corrosion resistance of the coatings was investigated. The results demonstrate that ATP@MBT was well dispersed, with MBT loading capacity up to 4.8 wt% and release rate up to 97.5 % at pH = 3. The results of electrochemical impedance spectra (EIS) and salt spray tests show that the addition of ATP@MBT enhances the corrosion resistance of the coatings. There are two explanations for the protective mechanism of the coatings containing ATP@MBT. The barrier function of ATP enhances the shielding ability of the integral coatings. When the coating is scratched, MBT loaded on ATP is released on the exposed region and forms an adsorption film on the aluminum alloy surface to protect the substrate.

Infrared radiation primarily contributes to the rise in car temperature, prompting excessive reliance on air conditioning, which in turn increases fuel consumption and emissions of harmful gases. Various methods exist to mitigate this, including the application of inorganic pigments designed to reflect infrared radiation. However, these pigments often come with colour limitations. Hence, there's a pressing need to develop a strategy capable of both reflecting infrared radiation and maintaining transparency in visible light, allowing for broader applicability across different colours. The goal is to reduce car temperatures, minimise air conditioning usage, and consequently decrease pollutant emissions. Our proposed solution involves utilising silica nano/microparticles known for their transparency in the visible spectrum and high reflectivity to infrared radiation. These particles are engineered with spherical morphology and varied sizes and combinations to identify the most effective approach. The most successful material we've developed showcases an impressive ability to increase the infrared (IR) radiation reflection and decrease the temperature by roughly 27 °C. Beyond their exceptional temperature-reducing capabilities, silica micro/nanospheres offer the added advantage of preserving the standard quality of paint. This study demonstrates a promising alternative to minimise the use of air conditioning systems and subsequently reduce the emission of polluting gases.

The synergistic improvement of corrosion protection and heat transfer properties has always been the challenge of coating research. In this article, the silicon carbide was hydrophobically modified and combined with blended fluorine resins to fabricate a multifunctional superhydrophobic coating by electrophoretic deposition. The prepared composite coating exhibits exceptional corrosion resistance (10¹⁰ Ω·cm² in 10 wt% H₂SO₄ at 60 °C for 50 days) and a heat transfer coefficient 1.26 times higher than the coating without fillers. The water contact angle of the composite coating surface is 160.5°, and the sliding angle is 2.3°, achieving a superhydrophobic state. The superhydrophobicity of the coating surface supports the barrier against corrosive media and droplet condensation, improving both corrosion protection and condensation heat transfer properties. It also has good thermal, wear and chemical stability.
