Abstract Despite tremendous advancements in icephobic coating technology, efficacy frequently declines or completely disappears low temperatures, high humidity, and dynamic environments. Here, a hyperbranched vanillin‐based composite with efficient properties (HVIC) is prepared by combining phosphazene compounds oil‐stored SiO 2 through imine bonds‐ HVIC exhibits excellent hydrophobicity, water sliding angle of 9°. This coating's exceptional slippery performance imparts outstanding non‐adhesive, self‐cleaning characteristics, deicing (τ ice : 8.2 kPa). It noteworthy that performs anti‐icing anti‐frosting low‐temperature humidity Compared superhydrophobic coatings (SHC), the icing delay time 9.1 times SHC, frosting extended roughly 300%. Most importantly, HVIC‐treated propeller experienced two ice‐shedding events during 200s test, while SHC lost its performance. can ensure normal operation equipment reducing energy consumption. The also significant UV shielding, antibacterial, flame retardant, self‐healing, recyclability properties. regarded as having potential for application due to easy scalable approach.

Superhydrophobic coatings with remarkable water repellence have emerged as an increasingly prominent field of research the growth material engineering and coating industries. address requirements several application areas characteristics including corrosion resistance, drag reduction, anti-icing, anti-fogging, self-cleaning properties. Furthermore, range applications for superhydrophobic has been substantially broadened by inclusion key performance features such flame retardancy, thermal insulation, resistance to penetration, UV transparency, anti-reflection, many more. Numerous endeavours focused on biomimetic materials because their distinct surface wettability. To develop a long lifespan, scientists refined processes preparation selection. accomplish repellency, are usually fabricated using harmful fluorinated chemicals or synthetic polymers. Utilising derived from biomass offers sustainable alternative that uses renewable resources in order eliminate consumption these hazardous substances. This paper provides insight researches reported construction lignin, cellulose, chitosan starch along techniques used constructing coatings. study is useful resource guidance selection various biobased polymers tailored specific applications. The further part put light different employed disciplines future perspectives

Polymer coatings decompose in the presence of UV radiation from sunlight and beget economic environmental losses. Hence, it is necessary to reinforce polymer with UV-blocking nanoparticles convert light into visible light. In this research work, surface graphene quantum dots (GQDs) was modified by vinyltrimethoxysilane (VTMS). VTMS-modified GQDs (VmGQDs) including 0, 0.3 0.6 wt% were taken account synthesize UV-curable epoxy acrylate/VmGQDs (Ep/VmGQDs) nanocomposite coatings. Surface modification, UV-blockage, fluorescence features viscoelastic properties Ep/VmGQDs analyzed various spectrometry tests. The existence VmGQDs (0.3 wt%) matrix led absorption rays regions emission area 578 nm wavelength (yellow fluorescence). Appearance strong bands at 250, 285 365 confirmed that a large portion absorbed blocked. intensity UV-blockage recorded >99%. Furthermore, reinforcement resulted increase storage modulus, cross-linking density Tg value.

Amidst the escalating energy demand, development of nonfossil, biorenewable, and sustainable resources becomes particularly pressing crucial. In this research, a biomass polyurethane acrylate (JPUA) derived from jatropha oil (JO) was successfully synthesized JPUAx composite coating fabricated by doping monolayer graphene (LG) nanoparticles. After rapid UV curing, has twice mechanical properties JPUA coatings, with tensile strengths up to 15.8 MPa, significant advantage over other coatings type, as well excellent corrosion resistance. The immersed in strong acid, alkali, high-salt solutions for 30 days negligible changes quality or surface morphology. Based on outstanding resistance JPUAx, fluorescent biobased prepared loading powders different colors, dual anti-counterfeiting system constructed combining Morse code. Fluorescent stickers have also been developed facilitate long-term encryption daily life. Overall, work not only expands synthesis strategy polymers nonfossil but provides an additional way multifunctional information applications.

Ice accumulation and moisture condensation pose significant challenges to the longevity performance of modern architectural materials. Superhydrophobic anti-icing coatings often suffer mechanical chemical degradation, particularly in outdoor settings subject heavy rain or impact. Additionally, most existing are airtight, leading humidity potential substrate deterioration, especially cement-based To address these challenges, we developed a nonfluorinated, breathable superhydrophobic coating by spraying PDMS-IPDI-TFB supramolecular network (PIT) mixed with polydopamine nanoparticles (PDA NPs). The optimized (PSC-40) exhibits high breathability, prevents blistering cracking, demonstrates exceptional durability. Remarkably, it withstands high-speed water jet impacts (We = 16,000) retains superhydrophobicity after damage. also possesses self-healing capabilities via hydrogen bonds dynamic covalent bonds, enabling recovery under sunlight, room temperature, underwater conditions. Its is evident from delayed freezing time (−15 °C) 1610 s significantly reduced ice adhesion strength (32.6 kPa). Under rapidly melts droplets layers within 138 695 s, respectively. This work introduces robust, anti/deicing capabilities, offering scalable solutions for outdoor, concrete-based applications.
