Icing accretion on the surface of an aircraft not only increases the weight but also causes changes in the surface shape, so there is an urgent need for anti-icing/deicing without shutdown. Here, a graphene-based film with light weight, super-hydrophobicity, high electric heat, and durability, which has both anti-icing properties and electrothermal deicing capability, is proposed. The film is prepared with 1 H ,1 H ,2 H ,2 H -perfluorodecyltrichlorosilane (FDTS)-modified SiO 2 /rGO wrinkles, and it has a micro-nanoscale hierarchical structure. Moreover, the superhydrophobic properties of the film can be controlled by adjusting the wrinkle size. Because of its good water repellency, the film can prevent and delay the freezing of water droplets at low temperatures. At −10 °C, compared to a smooth rGO film, the icing time of 10 µL supercooled water droplet on the micro-nanoscale hierarchical structured film can be delayed by ≈8.3 times, and the ice adhension decreases greatly. In addition, the film exhibits high-efficiency electrothermal properties. At −10 °C, under a low voltage of 15 V, the film can be heated rapidly to achieve rapid deicing and defrosting. The graphene-based micro-nanoscale hierarchical structure shows great potential in the field of sky anti-icing and real-time deicing.

The hydrophilicity and flammability of fiberboards have limited their real-life applications. In this study, a facile strategy for preparing the multifunctional coatings with superhydrophobicity and flame retardancy on medium density fiberboards (MDFs) has been investigated. The superhydrophobic and flame-retardant coating on the MDF surface was obtained by depositing polydimethylsiloxane (PDMS) and 1H, 1H, 2H, 2H-perfluorodecyltrichlorosilane (FDTS)-modified Mg/Al layered double hydroxide (LDH) particles step by step. The as-prepared coating exhibited superhydrophobic properties with a water contact angle (WCA) of ~155° and good self-cleaning properties. Furthermore, the limiting oxygen index (LOI) value of the superhydrophobic MDFs increased by 60.4% as compared to that of the pristine MDFs, showing improved flame retardancy. The peak heat release rate (PHRR) and total heat release (THR) of MDFs decreased after coating with PDMS@FDTS-Mg/Al LDH, suggesting that the superhydrophobic coating decreased the fire growth speed and risk of fire hazard of MDFs. This coating with multiple functions opens a new avenue for the protection and functionalization of MDFs.Keywords:medium density fiberboard;Mg/Al LDH;FDTS;superhydrophobicity;flame retardancy

Traditional methods for treating oily wastewater often face limitations of efficiency, cost-effectiveness, and adaptability to varying environmental conditions. In this study, a novel, cost-efficient modification technique was developed to produce superhydrophobic graphite felt (SGF) through a simple immersion process using 1H,1H,2H,2H-perfluorodecyltrichlorosilane (FDTS). The modified SGF demonstrated excellent superhydrophobicity and self-cleaning properties, with a water contact angle up to 157°, nearly 30° higher than that of unmodified graphite felt. Additionally, the SGF exhibited a remarkable maximum adsorption capacity of 4.29 g/cm3 for carbon tetrachloride and maintained stable performance across high-salinity, acidic, alkaline, and elevated-temperature environments. Notably, the material also displayed impressive photothermal conversion capabilities, enabling the rapid adsorption of viscous oils under sunlight without external energy input. For instance, the adsorption capacity for cyclohexanone increased to 1.6 g/cm3 within 20 s under light, almost ten times faster than in the dark. The underlying mechanism for photothermally enhanced adsorption was investigated. Furthermore, the SGF demonstrated outstanding efficiency and reusability in gravity-driven oil–water separation, with a service life more than five times longer than that of unmodified graphite felt. This work presents a low-cost, highly efficient adsorbent with photothermal enhancement for oily wastewater treatment, offering significant potential for sustainable environmental remediation and self-cleaning applications.

Perfluorodecyltrichlorosilane-based poly(dimethylsiloxane)-ZnO (FDTS-based PDMS-ZnO) nanocomposite coating with anti-corrosion and anti-fouling capabilities has been prepared using a one-step fabrication technique. XPS analysis and contact angle measurements showed the fluorine content to increase, while the hydrophobicity of the coatings decreased with addition of FDTS. XRD analysis revealed existence of ZnO nanoparticles of dimensions ranging from 11.45 to 93.01 nm on the surface of coatings, with the mean particle size decreasing with FDTS addition, and was confirmed by SEM and TEM observations. Interestingly, the anti-corrosion performance and mechanical properties of the coatings increased remarkably on addition of FDTS. Indeed, the observed low adhesion strength , surface energies and the outstanding anti-corrosive properties imply that the obtained coating would be useful in anti-fouling applications.

The increasing contamination of water resources by oily wastewater and human activities necessitates the development of efficient strategies for the remediation of polluted water sources. Due to the diversity of pollution sources, such as industrial wastewater, organic dyes, bacteria, and other complex pollutants, it is meaningful to develop a material capable of simultaneously treating these pollutants. The hydrophobic melamine sponge (PDMS@F-MOF@MS) was prepared using a simple impregnation method using zirconium metal-organic framework (UiO-66-NH 2 ), 1H,1H,2H,2H-perfluorodecyl trichlorosilane (FDTS), and polydimethylsiloxane (PDMS). The obtained PDMS@F-MOF@MS demonstrates remarkable superhydrophobic with a water contact angle of up to 156°. In addition, the PDMS@F-MOF@MS has robust adsorption capacity for a variety of organic solvents/oils (capable of absorbing 14.44 to 41.83 times its weight), a separation efficiency rate surpassing 95.9 %, and the ability to effectively separate oil-in-water emulsions. Furthermore, PDMS@F-MOF@MS demonstrates good mechanical properties and chemical stability, as well as good antibacterial and photocatalytic degradation properties. This project offers a valuable guide for the creation of versatile oil-water separation materials that can separate oil and water in variety of oily wastewater.

The modern portable and wearable electronic devices have been put forward a claim on flexibility, transparency and lightweight. Triboelectric nanogenerator (TENG) has attracted great attention as basic component of independent power source due to its outstanding characteristics. Here, a simple and efficient approach was demonstrated to modify poly-(dimethylsiloxane) (PDMS) in order to both improve the output electrical performance of TENG and optimize its hydrophobility as well. The 4 cm 2 TENG consisting of PDMS-perfluorododecyl trichlorosilane (FDTS) friction layer and copper nanowires (Cu NWs)/reduced graphene oxide (RGO) electrode, exhibits high output voltage and large transfer charge quantity of 125 V and 80 nC, where the corresponding electrical performances are larger with several times than that of pristine PDMS-based TENG. A voltage of 105.8V can be obtained even under the ambient condition with high humidity of ~60%. The improvements are attributed to the reaction between FDTS and PDMS, introducing fluorine element to absorb more electrons and increasing dielectric constant. Moreover, the fabricated TENG remains high visible transmittance (70.1%) and good flexibility as energy sources which can satisfy the demands of portable and wearable electronic devices.
