In this study, an Al₂O₃@EP@PDMS composite coating was successfully prepared on the surface of the wood substrate using the sand-in method to obtain a bifunctional coating with both superhydrophobic and flame retardant properties. It was found that the coating uniformly covers the surface of the wood substrate and provides mechanical, chemical and flame retardant properties such as abrasion and corrosion resistance. The limiting oxygen index (LOI) of superhydrophobic coated wood (SH-Wood) was increased from 19.8 % to 28.2 % for untreated wood (Natural Wood). CONE calorimetry tests showed that SH-Wood had 33.8 % less total heat release, 49.5 % less peak heat release, and a 23.2 % reduction in total smoke production, compared to Natural Wood by 23.2 %. The water repellency of the coating is greatly improved, with a water contact angle of 157° and a sliding angle of 2.3°. What's more, SH-Wood was exposed to different corrosive liquids and high temperatures of 100 °C, as well as tested by abrasion, peeling and scratching, which confirmed the excellent durability of the coating on the wood surface. The results of the study provide new ideas for the preparation of wood surface coatings with dual functions of superhydrophobicity and flame retardancy.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"204 ","pages":"Article 109244"},"PeriodicalIF":6.5,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143628892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, there is an immediate need to develop anti-counterfeiting solutions to identify or distinguish illicitly reproduced fake items among the genuine ones. Though several anti-counterfeiting technologies are available, security inks have garnered immense importance due to the diverse options of incorporating unique safety features in them. The present study demonstrates the formulation of a new, sustainable and stable mineral oil-free, invisible offset ink incorporating two types of fluorophores (DC-Red and UC-Green), which when printed on diverse substrates reveals distinctive identification features detectable through a specially designed single unit device. The prints obtained using the ink on various types of paper and fabric substrates reveal good photostability and adherence features. The printed samples display prominent red down-conversion fluorescence under 365 nm UV source and green up-conversion fluorescence upon shining with 980 nm laser beam in combination with a beeping audio response upon irradiating with 940–980 nm near-IR source using an IR taggant reader. These multi-level covert security features achieved using a single sustainable formulation are difficult to identify/replicate by the forger but can be easily validated by the user by means of the newly designed combi-reader. The smart programmable single unit combi-reader comprising of a buzzer together with UV and IR light sources is fabricated to authenticate the security features, rather than three independent devices with different light sources and detectors. Visually observable down-conversion and up-conversion fluorescence coupled with audible beeping that are detected using the new customizable combi-reader enables easy, rapid, and non-destructive identification as well as authentication of genuine products or documents.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"204 ","pages":"Article 109237"},"PeriodicalIF":6.5,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formulated inks exhibited desirable particle sizes below 1 μm and surface tensions of 24.65 and 26.62 mN/m, meeting the industry standards for optimal printing performance.

The <em>ΔE</em> values for color strength were desirably below 1 for AELO (0.83) and poly (AELO/MMA)-based inks (0.85), indicating color shifts imperceptible to the human eye and exhibiting high rub resistance.

By modulating the intensity and direction of the EF, HFBI proteins were precisely aligned and adsorbed onto the graphene surface. Molecular dynamics (MD) simulations revealed EF's influence on the interaction between HFBI and graphene, with a focus on the protein's electric and hydrophobic dipole moments. An EF of 0.05 V/nm maintained the structural stability of HFBI proteins, enabling effective adsorption onto the graphene surface. We verified that the hydrophobic dipole and helix patch orientation of HFBI proteins were significantly rotated when an optimal EF was applied along the <em>Z</em>-axis. Selective functionalization of the graphene surface was achieved by orienting the dipole moments of randomly distributed HFBI proteins (in up, side, or down positions) using an optimal EF (0.05 V/nm) along the <em>Z</em>-axis in either the Z-positive or Z-negative direction. Under a Z-positive EF, hydrophilic functionalization of the HFBI-Graphene composite was observed. Conversely, a Z-negative EF induced hydrophobic functionalization for HFBI proteins in the side and down positions, though not for those in the up position. We attributed this variation in hydrophilic/hydrophobic functionalization to the electrostatic interactions of charged amino acids. Furthermore, by employing HFBI protein mutants with charged amino acids, we successfully achieved hydrophobic functionalization of HFBI-Graphene composite.

In this paper, a novel kind of coatings with both anti-penetration and liquid-like functions were prepared through the strategy of grafting fluorinated side chains as molecular brushes onto the cross-linking network. A fluorinated polysiloxane containing sulfhydryl groups was first synthesized and a series of polysiloxane coatings were prepared through UV-triggered thiol-ene click reaction employing different types of olefins crosslinkers. The coatings cured with trimethylcyclotrisiloxane and tetraallylsilane exhibited superior anti-penetration properties for simulants, due to their higher glass transition temperatures, increased crosslink density, smaller free volume and the lack of groups interacting strongly with simulants. These two coatings also exhibited liquid-like properties owing to the smooth surface and the presence of fluorine-containing segments, enabling the simulants slide down the tilted surface with almost no contaminated traces left on the coatings. The high transparency of the coatings would broaden the application prospects of these coatings.
