“…Meanwhile, the high WCA (154.3°) can provide effectively passive protective performance of the coatings against the corrosive species. The successful grafting of SiO 2 particles on low-surface substances is the main reason for achieving superhydrophobicity . The SiO 2 coating presents a relative smooth surface are shown in Figure a.…”

Coatings with only passive protection cannot offer long-term anticorrosion on metals. Eco-friendly sustainable and responsive coating for active/passive corrosion protection is desirable to extend the service life of metals. Here, benzotriazole (BTA)-metal organic frameworks (Cu-MOFs, UiO-66) were embedded in silica (SiO 2 ) coating by one-step electrodeposition on copper. Combined with passive capability of MOFs and active protection of BTA inhibitor, the composite coating (BTA-MOF/ SiO 2 ) exhibited high and stable corrosion resistance, confirmed by microstructure characterizations and electrochemical tests. As a result, the as-prepared composite coating exhibited superhydrophobicity with a water contact angle of 154.2°. With loading of BTA-MOF in SiO 2 coating, the impedance modulus at 0.01 Hz increased by ∼10-fold and the corrosion current density decreased to 3.472 × 10 −9 A•cm −2 . Immersion and salt spray tests confirmed the long-term protection of the composite coating. The responsive release of BTA inhibitor endows the coating with a responsively anticorrosive behavior. The active-passive ability makes the coating a good candidate for protection on metals used in highly salty environments.

“…The different nanoparticles can avoid self-agglomerating single particles. The bonding and accumulation of nanoparticles of two sizes can create gaps, thus building a micro–nanostructure that facilitates resistance to moisture. , Furthermore, the rolling angle of the coating surface shown in Figure S6 is 9.8 ± 2° (<10°), indicating that the coating has good self-cleaning capabilities. The coating on the surface of sandstone exhibited a porous network structure with a thickness of 50–80 μm (Figure d,e).…”

“…As an inorganic material with stable chemical properties and the main component of sandstone, the nanoscale SiO 2 has excellent compatibility with the surface of sandstones . However, the micro–nanostructure constructed by nanoparticles and the low surface energy after modification are necessary conditions for the success of amphiphobicity. − Generally, it is often obtained by constructing surface roughness with inorganic particles and low surface polymer modification. The most popular approach in recent years has been to disperse nanoparticles in a polymer solution to form a polymer precursor composed of siloxane for the stone surfaces .…”

Exploring and developing an efficient protective coating for precious stone heritages that have been exposed to sunlight and rain for a long time is crucial. The UV resistance properties of nano-ZnO are apparent. Nano-SiO2 has a stable chemical structure and is one of the main components of stone. This paper introduces the synergistic protective effect of ZnO nanoparticles (ZnO-NPs) and SiO2 nanoparticles (SiO2-NPs) on stone, which is novel in this field. The functional nanocomposite coating (FZS coating) was obtained by spraying the ultrasonic mixture of ZnO-NPs and SiO2-NPs, cross-linked with a silane coupling agent, and modified by fluorocarbon. Wettability and UV aging tests showed that the sandstone deposited by FZS coating had excellent amphiphobicity (water contact angle (WCA) > 160°, oil contact angle (OCA) < 140°). The hydrophobicity was almost changeless after 300 h of UV irradiation, indicating high UV absorption capacity and durability. Interestingly, the amphiphobicity remains unchanged after alternating treatments of temperature and humidity, expressing superior weathering stability. This facile functional coating has potential applications protecting outdoor stone heritages.

“…Paper has attracted a lot of attention as one of the most used packaging materials, because of its wide range of sources, reusability, and biodegradability (Chen et al 2022). However, a rapid decrease in strength when it contacts water or moisture, and the poor oilresistant properties limit its application in many fields (Majeed et al 2013).…”

Recycled fibers are essential raw materials used by the paper industry. However, the strength of the formed paper may fall off excessively after several cycles of reuse of the fibers. Herein, the authors measured the changes in physical properties and fiber size after multiple recycling of fibers and prepared a handsheet from fiber recycled different times. Then the handsheets made with fibers that had been recycled 5 times were double-coated with nanocellulose derivatives to obtain oleophobic and hydrophobic paper. The first layer applied to the paper was cellulose nanofibril (CNF), and the second coating contained polydimethylsiloxane (PDMS) and CNF (CNFmp). The physical properties and barrier performance of coated paper were greatly improved compared to recycling paper. The water contact angle of the coated paper was as high as 139.8° and the Cobb60 value was 35.18±2.15 g/m2. The oil contact angle was 97.1°, and the oil kit number was 12/12.
