“…Coating is an essential step in adjusting the surface properties of materials. 1 Superhydrophobic coatings have received much attention because of their applications in elds such as selfcleaning, [2][3][4] non-wetting liquids, 5 anti-icing [6][7][8] and oil-water separation. 7,8 A superhydrophobic coating surface is usually constituted by a combination of low surface energy substances and micro/nanometer scale roughness structures.…”

“…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 ]. Up to now, a variety of methods have been developed to fabricate superhydrophobic surfaces on wood-based materials, such as hydrothermal treatment [ 7 , 8 ], sol-gel method [ 9 , 10 ], dip or spray-coating [ 11 , 12 , 13 , 14 ], soft lithography [ 15 , 16 ], “paint + adhesive” method [ 17 , 18 ], and so on. Among “paint + adhesive” methods, PDMS as adhesive has been successfully used to fabricate various robust and durable superhydrophobic surfaces [ 19 , 20 , 21 ].…”

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.

A Passive Anti-icing Strategy Based on a Superhydrophobic Mesh with Extremely Low Ice Adhesion Strength

et al. 2021

Although superhydrophobic materials have attracted much research interest in anti-icing, some controversy still exists. In this research, we report a cost-effective method used to verify the contribution of area fraction to ice adhesion strength. We tried to partially-embed silica nanoparticles into microscale fabrics of a commercial polyamide mesh. Then, the area fraction could be determined by altering the mesh size. Generally, the ice adhesion strength decreases as the area fraction decreases. An ice adhesion strength of ∼1.9 kPa and a delayed freezing time of ∼1048 s can be obtained. We attribute the low ice adhesion strength to the combination of superhydrophobicity and stress concentration. The superhydrophobicity prohibits the water from penetrating into the voids of the meshes, and the small actual contact area leads to stress concentration which promotes interfacial crack propagation. Moreover, our superhydrophobic mesh simultaneously exhibits a micro-nano hierarchical structure and a partially-embedded structure. Therefore, the as-prepared superhydrophobic mesh retained the icephobicity after 20 icing/deicing cycles, and maintained its superhydrophobicity even after 60 sandpaper-abrasion cycles and a 220 °C thermal treatment.
