Transparent coatings with self-cleaning and anti-fogging properties have received significant attention for their potential applications. In this paper, highly transparent porous silica coatings were fabricated on glass substrate through layer-by-layer (LBL) assembly of raspberry-like polystyrene@silica (PS@SiO 2 ) microparticles followed by calcination at high temperature. The as prepared coatings showed superhydrophilic property while displayed superhydrophobicity after chemical vapor deposition with low surface energy material. After two assembly cycles, the superhydrophobic porous silica coating had a water contact angle as high as 159°±2° with a sliding angle of 7°±1.5° and a transmittance of 85%. It is demonstrated that the number of assembly cycles affected the transmittance and wettability of porous silica coatings. In addition, the anti-fogging properties of the transparent superhydrophilic and superhydrophobic surfaces were investigated, presenting totally different fogging behavior.

A facile method to prepare surface self-concentration antibacterial coating with contact-killing mechanism was developed. Photo curable quaternary ammonium compound QAC bearing a 16-carbon alkyl chain and a terminal methacrylate was synthesized as reactive antibacterial additive. After UV irradiation, QAC was crosslinked in the soy-based coating matrix. With proper amounts of QAC, the UV cured coatings exhibited good properties such as high glossiness, good hardness and fine adhesion to cherrywood substrates. The self-concentration property of QAC on the cured coating surface, which is beneficial to reserve the physical properties of the bulk materials and to improve the surface antibacterial activity, was confirmed by fluorescence and X-ray photoelectron spectroscopy. Moreover, the introduction of QAC provided the coatings with superhydrophilicity property as well as good anti-fog capacity. The coatings with 8 wt% of QAC (charge density = 8.6 mol cm−2) exhibited almost 100% antibacterial activity against Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli by 5 log reduction. The contact-killing mechanism of coatings was confirmed via the zone of inhibition tests. The straightforward preparation combined with excellent antibacterial property makes the QAC containing coatings quite promising in antibacterial coatings realm and is suitable for industrial-scale manufacturing.

Dual-functional films with both antifogging and antibacterial properties have a wide range of applications on the surface of transparent materials. However, few studies have been reported so far about such dual-functional films. In this work, we developed self-healing poly(vinyl alcohol)/poly(acrylic acid)/Ag (polymer-Ag) composite films simultaneously with antifogging and antibacterial properties via a simple one-pot strategy. The antifogging property is attributed to sufficient hydroxyl groups of polymer. Ag nanoparticles obtained through thermal treatment were homogeneously distributed in the transparent composite films, and could inhibit the growth and lead to the death of bacteria such as E. coli . Polymer crosslinking and introduction of inorganic nanomaterial endowed the composite films with high mechanical robustness, and the films demonstrated the highest 5A adhesion grade, 8H pencil hardness, and endured washing test. What’s more, the composite films are capable of healing scratches caused by external forces. The robust yet self-healing dual-functional composite films with high performance by a simple mixing system would provide promising potential for their applications in various fields like medical devices, optical lens, goggles, and optical windows.

During the COVID-19 (Corona Virus Disease 2019) pandemic, traditional medical goggles are not only easy to attach bacteria and viruses in long-term exposure, but easy to fogged up, which increases the risk of infection and affects productivity. Bacterial adhesion and fog can be significantly inhibited through the hydrogel coatings, owing to super hydrophilic properties. On the one hand, hydrogel coatings are easy to absorb water and swell in wet environment, resulting in reduced mechanical properties, even peeling off. On the other hand, the hydrogel coatings don't have intrinsic antibacterial properties, which still poses a potential risk of bacterial transmission. Herein, an anti-swelling and antibacterial hydrogel coating is synthesized by 2-hydroxyethyl methacrylate (HEMA), acrylamide (AM), dimethylaminoethyl acrylate bromoethane (IL-Br), and poly(sodium-p-styrenesulfonate) (PSS). Due to the self-driven entropy reduction effect of polycation and polyanion, an ion cross-linking network is formed, which endows the hydrogel coating with excellent antiswelling performance. Moreover, because of the synergistic effect of highly hydrated surfaces and the active bactericidal effect from quaternary ammonium cations, the hydrogel coating exhibits outstanding antifouling performances. This work develops a facile strategy to fabricate anti-swelling, antifouling, and antifogging hydrogel coatings for the protection of medical goggles, and also for biomedical and marine antifouling fields.

Dual-functional emulsifying/antifogging polymeric micelles have been prepared by the self-assembly of poly(2-(dimethylamino)ethyl methacrylate-co-methyl methacrylate-co-7-acryloxy-4-methylcoumarin) P(DMAEMA-co-MMA-co-AOM). On one hand, the polymeric micelles have spherical morphology and exhibit triple responsive behaviors. The sample with the DMAEMA/MMA/AOM molar ratio of 5/3/3 (T2) is chosen to investigate the influence of pH on the emulsifying performance, and the configuration of polymeric micelles on the oil/water interface is investigated. The amount of micelles arranged on the surface of solidified polymerized beads gradually decreases as the pH changes from 12 to 5, and then total phase separation and demulsification occur at pH 3. On the other hand, we prepare an effective antifogging coating by forming an interchain network (ICN) resulting from self-assembled micelles and photo-cross-linked coumarin units. The ICN-T2 coating can not only absorb water vapor rapidly but also avoid excessive swelling of the amphiphilic terpolymer, thus leading to excellent antifogging performance. To the best of our knowledge, the photo-cross-linkable coumarin derivative is first introduced into an antifogging polymer coating at the molecular level, successfully avoiding the use of chemical cross-linking agents. The coumarin-containing polymeric micelle may be applied in many industrial processes and will provide new insight into the interface or surface property of macromolecular materials.

Carbon quantum dots (CQDs) with extended fluorescence lifetime and high quantum yield (>50 %) were successfully synthesized through a hydrothermal method from citric acid and polyethylene glycol (PEG) as carbon precursors. Then cetyltrimethylammonium bromide (CTAB) was used to modify CQDs. The as-prepared modified CQDs possess excellent dispersibility in both aqueous and organic media. When modified CQDs were incorporated into an acrylic resin matrix, the light conversion coating with good comprehensive properties was formed. The coating possesses high fluorescence quantum yield (16.52 %), the fluorescence lifetime (9.86 ns), low water contact angle (less than 10°), and high transmittance (>80 %). Also, the coating is characteristic of excellent anti-fog properties. The high-quantum-yield photoconversion coatings holds significant promise for applications in optoelectronic devices, advanced anti-counterfeiting systems, and efficient light-conversion technologies.

A novel route to construct stable and durable anti-adhesion surfaces was explored via a combination of the excellent anti-adhesion performance of zwitterionic betaine macromolecules with the strong adhesion of DOPA or its derivatives to various substrates. The zwitterionic betaine macromolecules bearing a thiol group poly(DMAPMAPS-co-BAC) and a DOPA derivative DMA containing a catechol anchor group and a double bond were first designed and synthesized. The poly(DMAPMAPS-co-BAC)-grafted surfaces were then fabricated via the interfacial thiol–ene photoclick reaction between poly(DMAPMAPS-co-BAC) and DMA anchored onto substrate (i.e., Glass slides and flat PET sheets) surfaces. The chemical formation of each layer on the surfaces was confirmed by XPS and ATR-FTIR analyses. Their morphologies and wettability were characterized. The results indicate that, compared with the original surfaces, the modified surfaces possess an increased nanoscale roughness; the WCA and OCA values on the modified Glass/PET surfaces can reach 10°/12° and 156°/162°, respectively, showing their strong hydrophilicity and excellent underwater superoleophobicity. The anti-oil-fouling and antifogging properties were investigated and the anti-bacterial adhesion properties were evaluated by bacterial adhesion tests using E. coli and S. aureus as test bacteria, respectively. The results show that the modified surfaces possess obvious anti-oil-fouling and antifogging properties and a strong ability to resist bacterial adhesion with a long term stability. It suggests that such a facile yet universal strategy based on interfacial thiol–ene photoclick chemistry could offer an effective solution to the poor stability of anti-adhesion surfaces modified with ultralow-adherent zwitterionic betaine macromolecules, and could be applicable to a wide variety of substrates.

Biofouling often occurs simultaneously with fogging, presenting significant challenges to visibility, safety, and operational efficiency. The development of biocompatible coatings that offer both antifouling performance and stability under fogging conditions is highly sought after. A method to form multifunctional coatings is presented, utilizing a zwitterionic nanocellulose composite material that demonstrates both antifogging and antifouling properties, suitable for application on various surfaces. Cellulose nanofibers are modified with lysine to impart zwitterionic characteristics, enhancing hydrophilicity and antifouling performance. Polyacrylic acid is incorporated as a binder, ensuring tight integration of the zwitterionic cellulose nanofibers, which further improves coating uniformity, stability, and adhesion. The resulting coating exhibits superior antifogging properties, excellent adhesion resistance, and mechanical strength while remaining nontoxic to biological organisms. This coating effectively addresses practical needs in applications such as medical endoscopy, food preservation, and marine antifouling. The research offers new insights and approaches for the development of eco-friendly and transparent protective coatings.

Hydrophilic anti-fogging coatings face dual challenges of insufficient water resistance and poor weathering durability in practical applications. To address these issues, we propose a natural composite coating system integrating hyaluronic acid (HA), glycerol (Gly), FeCl 3 , and zinc oxide nanoparticles (ZnO-NPs) via a facile mixing strategy. Inspired by the mucin-mediated hydration dynamics of tear films, the HA framework constructs a self-replenishing layer to inhibit fogging while achieving underwater oleophobicity through surface hydration, effectively repelling oily contaminants. Glycerol maintains flexibility and hydration equilibrium through hydrogen-bonded water retention, whereas FeCl 3 crosslinking enhances mechanical strength and water stability via dynamic coordination bonds emulating tear film's ion-modulated self-repair, thereby resisting hydration-induced degradation. ZnO-NPs further endow the coating with photo-induced hydrophilicity. The optimized coating exhibits exceptional water resistance, weathering durability, and mechanical robustness, retaining high transmittance and stable hydrophilicity after 120 h of water immersion, 120 h of xenon lamp irradiation, 40 adhesion cycles, and 300 abrasion tests. Remarkably, the coating demonstrates rapid self-healing within 10 s and superior self-cleaning performance. This study proposes a sustainable strategy to synergistically enhance water resistance and weathering resistance.

Icing and fogging on optical material surfaces bring various problems in daily life. Recently, some photothermal coatings have been reported to prevent the condensation or freeze of water droplets by increasing the surface temperature. However, it is a great challenge to apply them in practical conditions due to their opaqueness and poor mechanical wear-resistant property. In this work, we constructed a robust transparent photothermal omniphobic coating with a simple dip-coating technique. In the coating system, photothermal polypyrrole nanoparticles are introduced into inorganic silica networks, and then polydimethylsiloxane (PDMS) brushes were grafted on the inorganic silica layer to endow the surface with omniphobicity and stain resistance. The transparency and photothermal capacity of the coating can be regulated by the deposition times of the coating. In addition, the coating has an excellent anti/deicing property and reduces ice adhesion obviously due to the existence of “liquid-like” PDMS brushes. More importantly, the coating presents outstanding mechanical wear-resistant and self-lubricating properties that can endure several thousand friction cycles without performance loss. The mechanically robust photothermal omniphobic coating gives a feasible approach to anti-icing and antifogging of transparent substrates under sunlight irradiation.

Inorganic coatings with high transparency and superhydrophilicity have attracted tremendous attention because of their potential applications in marine environment monitoring, and oily wastewater treatment. However, the transparency and superhydrophilicity are usually mutually exclusive. Herein, we present a new facile strategy for fabricating highly transparent and mechanically robust superhydrophilic inorganic coatings with outstanding anti-fogging ability and anti-oil-fouling performance for high-viscosity oils. In this strategy, amorphous calcium phosphate (ACP) coatings are mineralized on the surface of polydopamine and polyethylenimine (PDA/PEI) membranes under the synergistic effect of magnesium ions, citric acid, and poly(acrylic acid) at room temperature, forming an organic-inorganic composite structure with a uniform texture on various substrates. Owing to the strong hydration capacity of ACP, these coatings are highly efficient at preventing surface fogging and avoiding underwater crude oil fouling. Meanwhile, the ACP coating without grain boundaries or pores can reduce light scattering, thus maintaining the high transparency of the substrate. Moreover, the organic-inorganic composite structure endows the coatings with robust mechanical properties. This PDA/PEI-ACP mineralized coating can be deposited on various substrates, showing potential applications in underwater optical lenses, oily wastewater treatment, microfluidic devices, and other areas.
