In this work, we develop a simple yet robust method to fabricate a bioinspired adhesive coating based on polyethyleneimine (PEI) and tannic acid (TA) complexes, exhibiting excellent antifogging, self-cleaning, and antibacterial properties. The polyethyleneimine-tannic acid (PEI-TA) complexes coating combined with the bioinspired adhesive property from TA can be effectively and stably coated onto various substrates through a one-step deposition process , and the hydrophilicity of the coated substrates can be significantly enhanced with their water contact angle less than 10°. The bioinspired adhesive coating endows the coated substrates with outstanding antifogging and self-cleaning performance. Moreover, it is found that the PEI-TA coated safety goggles display excellent durability and antifogging capability compared to the commercial antifogging safety goggles and commercial antifogging agents coated safety goggles under 65 ℃ vapor condition for 2 h. Furthermore, the PEI-TA coatings show superior antibacterial activities for Gram-negative Escherichiak coli and Gram-positive Staphylococcus aureus . The antifogging, self-cleaning, and antibacterial coating provides widely potential application prospects in optical and medical devices .

Hydrophilic coatings, an effective strategy to achieve anti-fogging performance on substrates, still face the problem of poor endurability. In this work, a hydrophilic antifogging coating consisting of poly (2-acrylamido-2-methylpropanesulfonic acid- co -butyl acrylate- co -dopamine methacrylamide) was constructed, which shows significant anti-fogging performance, notable abrasion resistance and excellent adhesion. The combination of strong interfacial adhesion and hydrophilic/hydrophobic structure is key to this approach, which avoids interfacial failure and swelling-induced wrinkles under typical fogging conditions. The adhesion strength is higher than most commercial glues and high-performance polymer adhesives in the literatures since the catechol groups endows the coating marvelous adhesion to the substrate. This study provides a promising avenue for the design and fabrication as well as practical application of anti-fogging coating with strong adhesion strength.

Inspired by the repair of DNA through efficient reformation of hydrogen bonds (H-bonds), herein we report a facile one-step approach to construction of self-healing antifogging thin films on the basis of partly cross-linked poly(vinyl alcohol)(PVA) and poly(acrylic acid)(PAA). By designing the molar ratio of hydroxyl groups to carboxyl groups, the cross-linked polymer thin films maintain abundant free hydroxyl groups to present excellent antifogging property, which is derived from the hydrophilicity and hygroscopicity of the thin films. The thin films showed smart intrinsic self-healing characteristics towards wounds caused by external forces, which is attributed to sufficient free hydroxyl groups at the scratched interfaces to reform H-bonds across the interfaces and a sufficient chain mobility that is indispensable for chain diffusion across the interfaces and hydroxyl groups association to form H-bonds. No synthetic surfaces reported so far possess all the unique characteristics of the polymer thin films: intrinsic self-healing, long-term antifogging, excellent mechanical property, high transmittance and large-scale feasibility.

Using clean and renewable solar energy, photothermal technology has garnered significant attention from researchers. Photothermal materials possess the capability to efficiently convert solar energy into thermal energy. In this work, polydopamine (PDA)- poly (vinyl alcohol) (PVA) coatings with outstanding antifogging performance assisted by light illumination were fabricated by a one-step scrape coating method at room temperature. PDA with excellent photothermal properties and strong adhesion to substrate was applied in combination with PVA as matrix. Carbon dots (CDs), which had previously been found as nano-crosslinkers to form abundant hydrogen bonds with hydroxyl groups of PVA and substrate, was used to enhance the mechanical robustness and the adhesion to substrate of coatings, producing a synergistic effect with the PDA. The coatings had an average transmittance exceeding 80 % in the visible region. Under xenon lamp with light intensities of 60, 80 and 100 mW cm −2 at the coating location, the temperature of the coating surface rose to 40.2, 46.1 and 53.1℃, respectively. Under xenon lamp with a light intensity of 100 mW cm −2 at the coating location, the antifogging duration when exposed to hot steam 5 cm above a 60 °C water bath was three times more than that without xenon lamp illumination. The coating remained unaffected even after immersion in water and various solvents for 2 h, without showing any signs of folding or damage. The coating exhibited a pencil hardness of up to 8 H and adhesion-to-substrate of up to 5 A, and was able to withstand the Taber wear test for 4000 cycles. The preparation method is simple and efficient, and may be applicable to a wide range of optical, optoelectronic, medical scenarios.

AbstractIn this work, a multifunctional coating was developed by grafting a zwitterionic poly[2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)-co-acrylic acid [poly(SBMA-co-AA)] polymer onto a glass slide, which possesses excellent antifog, antifrost, and self-cleaning properties. These properties are attributed to the strong hydration of the hydrophilic zwitterionic PSBMA segments. The durability of the coating can be improved because the carboxyl group (–COOH) of the PAA segment enables formation of a robust covalent bond with the amino group (–NH2) on the substrate. The coating presents long-term stability, as proved by water contact angles, which were stable at 12 ± 1° after exposing the coating in ambient environment for 60 days or immersing in deionized water for 24 h. In addition, the underwater oil contact angle measurement demonstrated that an oil stain on the zwitterionic poly(SBMA-co-AA) polymer coating can be easily removed upon contact with water, showing self-cleaning performance. These properties verified that the zwitterionic multifunctional coating exploited in this research has many potential application prospects, including construction, automotive, aerospace, shipbuilding, biomedical, and other optical fields.Graphic abstract

The inevitable presence of fog causes a loss of light transmission in optical materials and leads to many unacceptable and serious consequences. A promising strategy for avoiding fog is to modulate the wettability of the material surface and further change the formed way of droplets. Although many works achieved high antifogging coatings, they are lack of the long-lasting antifogging at varied conditions. In this work, a high adhesion strength and persistent antifogging capability hydrophilic coating is obtained by utilizing silane coupling agents containing double bonds such as triethoxyvinylsilane (A151) and 3-(trimethoxysilyl)propyl methacrylate (KH570) with 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and then compositing with poly(vinyl alcohol) (PVA). The coating composed of A151 has a relatively uniform and flat surface structure, due to weaker hydrolysis ability of A151 promoted the smooth condensation speed, compared to KH570. Thanks to the hydrophilic and hydrophobic balance properties of the A151-modulated coating network, the resultant coating exhibits good antifogging performance in the range of 0 °C to 90 °C, which keeps a light transmission of about 85 %. Surprisingly, the coating shows excellent adhesion (350–700 kPa) to the substrate, which is significantly better than other conventional hydrophilic antifogging coatings, and the hydrophilic and hydrophobic modulation capability and the enhanced interfacial adhesion of A151 segments provide the basis of the coating for long-lasting antifogging, which would open up a new way of durable hydrophilic antifogging coatings.

Hydrophilic coating can prevent surface from fogging but its application is limited by low mechanical performance. In this study, a hydrophilic coating was prepared by crosslinking the Si-doped carbonized polymer dot (Si-CPD) with 3-glycidyloxypropyltrimethoxysilane (GPTMS) and ethylene oxide (EO). The hydrophilic coating can be used as robust hydrophilic anti-fogging coating. The Si-CPD derived from ethylene diamine tetraacetic acid (EDTA) and aminopropyl oligosiloxanes (APOS) was successfully prepared via one-step hydrothermal method . Then, a resin solution was prepared by mixing Si-CPD, GPTMS and EO. Epoxy group of GPTMS and EO can react with amino group of Si-CPD. Finally, a composite coating with antifogging function can be obtained by simple heating curing. Due to the introduction of hydroxyl which derived from EO, the coating shows excellent antifogging performance. Meanwhile, the presence of inorganic component endows the coating with outstanding mechanical performance. The coating has great potential in related applications, such as optical lenses, mirrors and other transparency substrates.

Hydrophilic anti-fogging coating has become a research hotspot due to its good anti-fogging performance and easy preparation. In this work, a zwitterionic anti-fogging coating with anti-fouling and self-healing properties was prepared by (Methacryloyloxy)ethyldimethyl-(3-sulfopropyl) (SBMA) and Itaconic acid (IA). And the antifogging performance of the coating has been improved due to -COOH from IA. The high light transmittance (over 95%) can be observed after anti-fogging test. We use amide bonds to connect the coating to the glass slide, which greatly improves the water resistance and durability. The coated glass can maintain anti-fogging property after being immersed in water for 7 days or stored for over 200 days. Results show that the anti-fogging coating has good self-healing function and oil stain resistance. The contact angle of the coated glass slide is 8.17°, and shows a good super hydrophilicity. This anti-fogging coating provides great potential for applications in medical, food industry, transportation .etc.

Multiple functional coating is urgently needed in complex service surroundings to meet various requirements. In this work, a brush-like amphiphilic copolymer of poly methacryloxyethyl dimethyl butyl ammonium bromide–polydimethylsiloxane (pMDBAB–PDMS) was synthesized to construct an environment-adaptive multifunctional coating based on the copolymer via the UV-curing method. The special molecule chains of the copolymer assembled predominately on the coating surface in different surroundings, which rendered the surface with various functions. In water-rich surroundings, the hydrophilic quaternary ammonium groups in the coating endow the coating surface with antifogging, oleophobicity underwater, self-cleaning, antibacteria, triboelectric resistance, and super lubrication properties. In dry air surroundings, the long, flexible, low surface energy molecular PDMS chains tend to distribute on the top of the coating surface, which gives a low friction coefficient and antioil properties. This work presents a strategy to construct environmental adaptive coating that has an important application prospect in the field of optical lens.

Preventing the appearance of fog on transparent glass is an important issue not only in our daily lives but also in scientific research and clinical diagnosis. A zeolite molecular sieve with MFI-type structure was identified as a very promising antifog material. In this work, MFI zeolite films with different microstructures were prepared by the solvothermal secondary growth method using diols including ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG), and tetraethylene glycol (tEG) as solvents. The elimination mechanism of new MFI twin crystals was demonstrated based on scanning electron microscopy (SEM), X-ray diffraction (XRD), and transmission electron microscopy (TEM) characterizations of the resulting films and the mother solutions. The twin-free MFI films with b-axis preferred channel orientation exhibited both higher light transmittance and lower haze compared with the a-&b-mix-oriented film. The employment of diol solvents facilitated the generation of a surface Si–OH group on the films, leading to the improvement of film hydrophilicity. By taking advantages of the high transparency and hydrophilicity, the b-oriented MFI films synthesized on glass substrate achieved good antifogging performance.

Superhydrophilic SiO 2 coatings offer unparalleled advantages in terms of antifogging properties. However, they show suboptimal mechanical abrasion resistance and environmental durability, limiting their application. Accordingly, research has focused on the trade-off between hydrophilicity and mechanical abrasion resistance as well as between environmental durability and visible transmittance in superhydrophilic SiO 2 coatings. Herein, a composite-structure coating with a densely distributed particulate phase and enhanced crosslinking strength is developed without the use of organic compounds. The coating exhibits remarkable transparency and antifogging properties, with an average transmittance similar to that of bare glass and a water contact angle of approximately 0°. Moreover, the coating exhibits impressive hardness and adhesion of up to 4H and 5B, respectively. The coating retained its antifogging properties even after undergoing 500 cycles of wear induced using a 3000-mesh sandpaper, impact of sand (40 g) dropped from a height of 40 cm, 10 weeks of exposure to the outdoor environment, and 25 h of immersion in water. The test results demonstrate that the coating exhibits satisfactory mechanical abrasion resistance and environmental durability, which are essential for its practical applications. The composite structure formed using linear SiO 2 molecules as crosslinking agents with spherical SiO 2 nanoparticles considerably enhances the adhesion and abrasion resistance of the coatings. Overall, the developed composite-structure coatings will facilitate their commercial viability and expand the application of superhydrophilic materials in various research fields.

A dual-cure hydrophilic acrylate polymer was synthesized via radical polymerization with acrylic acid (AA), isophorone diisocyanate (IPDI), 2-acrylamide-2-methylpropane sulfonic acid (AMPS), hydroxyethyl acrylate (HEA), and 3-(trimethoxysilyl)propyl-2-methyl-2-methacrylate (MPS) as monomers, then used as prepolymer for antifog coating with tetraethylorthosilicate (TEOS) as a novel crosslinker. The prepolymer was mixed with crosslinking agent and photoinitiator to form coating formulas. The coating was characterized by nuclear magnetic resonance (NMR), Fourier-transform infrared (FTIR) spectroscopy, and contact angle measurements. The results indicated that the dosage of AMPS and TEOS had great influence on the antifog performance. With an increasing TEOS amount, the hardness, adhesion, water resistance, impact resistance, and thermal stability of the films were improved, at the expense of transparency; with increasing dosage of AMPS, the hydrophilicity of the film increased at the expense of water resistance. Optimum coating properties could be obtained when the amount of AMPS was 7% and that of TEOS was 5.5%. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) results showed that some SiO 2 microspheres were formed and microphase separation occurred between the macromolecular segments, yielding the excellent coating properties.
