Hydrophilic coating is a promising strategy but suffers from the complications of the manufacturing method as well as the lack of longevity. Herein, we report an antifouling and lubricating hydrophilic coating based on zwitterionic copolymer poly(2-Methacryloyloxyethyl phosphatidylcholine-<em>co</em>-hydroxyethyl methacrylate-co-(Benzoyl)phenyl methacrylate (poly(MPC-<em>co</em>-HEMA-<em>co</em>-BP)) through pre-gel solution spin-coating followed by UV-curing. The poly(MPC-<em>co</em>-HEMA-<em>co</em>-BP (PMHB) coatings possess hygroscopic properties that facilitate the formation of a hydrated layer, thereby leading to friction reduction. Moreover, both antibacterial and protein resistance tests substantiate the exceptional antifouling characteristics exhibited by the PMHB coating. Furthermore, after 7 days of coincubation, the antibacterial rates of PMHB coatings against <em>Escherichia coli (E. coli)</em>, <em>Staphylococcus aureus (S. aureus)</em>, <em>and Proteus mirabilis (P. mirabilis)</em> are 72.98 %, 75.11 %, and 88.23 %, respectively. Subsequently, PMHB coating reduced the attachment of encrustation in a 7 days artificial urine cycling experiment.

In this study, we present a method to impart flame retardant (FR) and insect repellent (IR) properties to nylon-cotton blends. Flame retardancy was achieved by covalently attaching phytic acid, a bio-derived material, to the hydroxyl groups of cotton in nyco fabrics. Subsequently, these FR-treated nyco fabrics were coated with an acylate-based monomer along with permethrin to confer insect-repellent properties. FTIR-ATR spectroscopy confirmed the presence of weight of phytic acid on nyco fabric and the weight gain from this was 6 % with respect to initial fabric weight. The multifunctional fabrics exhibited a 200 % increase in char formation upon thermal degradation compared to untreated nyco. Moreover, the multifunctional fabrics demonstrated self-extinguishing properties with a char length of <15 cm, whereas untreated fabrics burned completely. In cone calorimeter experiments, FR-treated fabrics showed a reduction of over 25 % in total heat release compared to untreated controls. The addition of FR facilitates char formation and the release of non-flammable gases such as water vapor (H<sub>2</sub>O), carbon dioxide (CO<sub>2</sub>), and ammonia (NH<sub>3</sub>), suggesting a condensed phase mechanism of FR action as evident from TGA-FTIR evolved gas analysis.

When applied as a coating to jute, cotton, polyester fibers, PU sponge, and wood, they became superhydrophobic, with WCAs ranging from 154.7 to 161.2° except for the wood substrate, which achieved a WCA of 132° (±3°). The coated polyester fabric exhibited remarkable durability, retaining consistent WCA values after 70 abrasion cycles, 75 adhesive tape peelings, and 20 detergent washing cycles. It also showcased excellent self-cleaning properties, effectively repelling dust and various liquids. Additionally, the coated PU sponge demonstrated exceptional performance in separating oil from different oil/water mixtures, achieving rapid separation of organic solvents within seconds and maintaining a separation efficiency of over 98% even after 12 reuse cycles.

Inspired by the structure of honeycombs, this paper introduces a bilayer, nested, porous self-healing microcapsule featuring an ultra-thin, rigid shell that effectively addresses the above challenges. An ultra-thin rigid shell is first constructed to enhance mechanical strength while significantly increasing the load capacity of the healing agent. Subsequently, the subcritical water treatment method is employed to etch nanoscale through-holes on the shell surface for encapsulating the healing agent. Finally, via a cross-linking reaction, a film is formed on the surface of the porous shell to seal the holes. The test results show that the loading efficiency of the microcapsules achieves 94.4 %. Moreover, while the repair efficiency is substantially enhanced, the intrinsic properties of the matrix material are maintained, and there is additionally a measurable improvement in tensile strength and insulation performance. To our knowledge, the microcapsules that significantly enhance repair efficiency while concurrently improving the properties of the matrix have not yet been reported in previous studies.</p></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":null,"pages":null},"PeriodicalIF":6.5,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142086873","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}
