“…Meanwhile, several new absorption bands were observed at 2960 cm −1 , 2850 cm −1 , 1710 cm −1 , 1005 cm −1 , 913 cm −1 and 470 cm −1 assigned to asymmetric –CH 3 , symmetric –CH 2 , –COO stretching, (Si, Al)–O asymmetric stretching, Al-OH and (Si, Al) –O bending from the STA-KL particles, respectively [ 36 , 37 ]. In addition, the absorption band at 1099 cm −1 (Si–O–Si stretching) was also observed from PDMS [ 4 , 16 ]. These results demonstrated that the PDMS@STA-KL coating was successfully covered on the LC.…”

The disadvantages such as swelling after absorbing water and flammability restrict the widespread applications of lignocellulose composites (LC). Herein, a facile and effective method to fabricate superhydrophobic surfaces with flame retardancy on LC has been investigated by coating polydimethylsiloxane (PDMS) and stearic acid (STA) modified kaolin (KL) particles. The as-prepared coatings on the LC exhibited a good repellency to water (a contact angle = 156°). Owing to the excellent flame retardancy of kaolin particles, the LC coated with PDMS@STA-KL displayed a good flame retardancy during limiting oxygen index and cone calorimeter tests. After the coating treatment, the limiting oxygen index value of the LC increased to 41.0. Cone calorimetry results indicated that the ignition time of the LC coated with PDMS@STA-KL increased by 40 s compared with that of uncoated LC. Moreover, the peak heat release rate (PHRR) and the total heat release (THR) of LC coated with PDMS@STA-KL reduced by 18.7% and 19.2% compared with those of uncoated LC, respectively. This LC coating with improved water repellency and flame retardancy can be considered as a potential alternative to protect the lignocellulose composite.

“…Inspired by natural lotus leaves, superhydrophobic coatings have gained tremendous research interest for improving hydrophobicity of wood-based materials [ 4 , 5 ]. It is well known that the formation of superhydrophobic surfaces is attributed to the dual function of micro/nano- hierarchical roughness and low surface energy [ 6 ].…”

“…Wettability refers to the spreading ability of the liquid on a solid surface and is quantified by the contact angle. A solid surface with a water contact angle (CA) higher than 150° [1][2][3][4]is a superhydrophobic surface; when the CA of a surface is less than 5°, it is called a superhydrophilic surface. These surfaces have been intensely investigated in different domains thanks to their wide applications in various technical areas such as drag reduction [5], self-cleaning [6][7], anti-icing [8][9][10], anti-corrosion [11][12], oil/water separation [13][14], etc.…”

Extreme wettability surfaces have attracted more and more attention due to their practical applications, however, few reports have shown a universal method to create surface patterns with extreme wettability on a variety of metals. In this paper, a mask-assisted dual-chemical-processing approach without special modification is used to prepare the extreme wettability patterns on various metal substrates. Fabrication of superhydrophilic-superhydrophobic patterns on five kinds of metal substrates of Al, Ti, steel, Zn and Mg alloy proved the versatility of this method. The extreme wettability patterns prepared by this method were applied to fog harvest and we found the big differences in the collection efficiency of various metal surface patterns.

“…Tu reported a method for fabrication of a durable and self-healing superhydrophobic coating on Chinese fir wood. This coating was obtained by two steps, including coating a polydimethylsiloxane (PDMS) film and then spraying a mixture of perfluoroalkyl methacrylic copolymer and TiO 2 nanoparticles [ 17 ]. Kong prepared superhydrophobic and flame-retardant ZnO coating on wood by a hydrothermal process.…”

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.
