“…[10][11][12] Reduced roughness increases the contact area between liquids and surfaces, whereby the hydrophobicity would be easily lost. 13 Hierarchical micro-nano scale morphology structures are ideal for resisting contamination or abrasion damage, 14,15 and are more likely to maintain surface roughness aer damage than single structures. 16 Among hybrid organic-inorganic building blocks, polyhedral oligomeric silsesquioxane (POSS) has attracted signicant research effort.…”

“…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 ]. However, there are few studies on the fabrication of lignocellulose composites superhydrophobic coatings.…”

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.

“…[ 24 ] Polysiloxane‐based coatings, in contrast, result in robust coatings, which, however, have a reduced thermal stability and a slower rate of crosslinking, when compared to polysilazanes. [ 10,35 ] Also liquid release agents are available. These agents, however, can contaminate the surface of the shaped part, which may have a negative effect on further processing steps, requiring a posterior cleaning of the shaped part.…”

Polysilazanes are excellent coating materials, because of their self‐crosslinking in air at low temperatures, high chemical and thermal stability, elevated hardness, and excellent adhesion to many different substrates. Therefore, coatings of two chemically different polysilazanes (crosslinked Durazane 1800 (HTTS)/perhydropolysilazane (PHPS)) are deposited by either dip or spray coating and crosslinked at 200 or 300 °C in air to investigate the chemical composition, surface energy, and coating adhesion in dependency on the precursor type and crosslinking temperature. The silazane HTTS possesses a higher amount of nonpolar organic groups resulting in a lower surface free energy. The anti‐adherence properties are investigated by using a phenolic resin via pull‐off adhesion, which is slightly reduced from 13 MPa for uncoated aluminum to less than 10 MPa for HTTS coated substrates. The addition of different amounts of poly(tetrafluoroethylene) (PTFE) particles causes a remarkable reduction of the surface free energy leading to a strongly reduced pull‐off adhesion of less than 4 MPa of the phenolic resin from the HTTS/PTFE coated substrates. The anti‐adherent properties remain even after repeated pull‐off tests. Because of the excellent properties, the HTTS/PTFE coatings are a very suitable system for easy mold release of plastic parts from metal molds and to replace commercial nonstick PTFE coatings.
