“…The Wenzel and Cassie–Baxter states are two main models used to explain the behavior observed under droplets on rough hydrophobic surfaces. In the Wenzel model, a droplet is in contact with the entire solid surface and completely penetrates into the cavities, while in the Cassie–Baxter model, , a droplet is suspended on the surface features and the air bubbles are trapped in cavities on the rough surface. Samples showing CA values higher than 150° and very low SA values (not more than 10°) can be considered as superhydrophobic.…”

Superhydrophobic starch-based films were prepared using poly(dimethylsiloxane) (PDMS) and ball-milled montmorillonite (MMT) coating. The hydrophilic and moisture-sensitive starch-based films coated with PDMS could create a hydrophobic surface with a static contact angle of water up to 115.2 ± 1.2° but could not achieve superhydrophobic behavior. On the other hand, the starch-based film sprayed with MMT could achieve superhydrophobic behavior, but the adhesion between the starch matrix and MMT was weak. In this work, a spraying–immersion method was developed for coating starch film with PDMS and ball-milled MMT. The surface of the treated starch-based film had a contact angle of up to 159.1° and a sliding angle of 3.6°. SEM, TEM, XRD, particle size analysis, and optical profilometry were used to study the effects of PDMS and MMT on the surface properties of starch-based film, in particular PDMS/MMT ratio, MMT particle size, and preparation technologies. The results show that the hierarchical structure obtained by PDMS assisted by ball milling MMT provides the appropriate roughness to create low hysteresis superhydrophobic starch film. Increasing ball-milling time could increase the surface area and roughness, which results in increasing contact angle.

“…40 Many researchers have exploited MoS 2 in the field of oil/water separation in recent years, and have achieved some progress. [41][42][43][44][45] Guo et al 44 reported the MoS 2 -ODA (octadecylamine)-Fe 3 O 4 @PU composites via simple ultrasonic loading-drying cycle technique, which exhibited the WCA of 161.64 and adsorption amount 60-109 wt wt À1 with the MoS 2 solution concentration of 0.2 g * 50 mL À1 . Furthermore, because of the presence of MoS 2 , MoS 2 -ODA-Fe 3 O 4 @PU has superior photodecomposition capabilities, making it suitable for the photodegradation of organic pigments in wastewater.…”

Oily wastewater has caused serious damage to the human health and ecological environment. It is urgent to develop novel materials for high performance oil/water separation. Porous melamine sponges (MS) are considered as an ideal matrix material for oil/water separation. Herein, molybdenum sulfide (MoS2) modified with tannic acid (TA) and octadecylamine (ODA) was attached to MS framework via a facile dip‐coating method. This novel and eco‐friendly MS@(MoS2@ODA) sponge displays superior superhydrophobicity (WCA = 156.2°) and oil/water separation ability (absorption capacity = 113–145 g g−1). MoS2@ODA not only enhances surface roughness of MS framework, but also raises its specific surface area, causing an increase in the oil adsorption capacity of MS. Moreover, the composite sponge exhibited excellent chemical and mechanical stability. It is envisioned that this work can demonstrate a facile synthesis strategy for producing environmental friendliness MS with stable superhydrophobicity for high‐efficient oil/water separation.

“…Shen et al developed a dipping-UV curing method to fabricate superhydrophobic coating by using vinyl-terminated polydimethylsiloxane and 3-methacryloxypropyl trimethoxysilane modified molybdenum disulfide. [32] Liao et al proposed a dipping-UV curing approach to fabricate superhydrophobic hybrid coating on the surface of polyester fabric for oil/water separation by using (3mercaptopropyl) trimethoxysilane modified graphene oxide and vinyl-terminated polydimethylsiloxane. [33] However, these coatings have poor self-cleaning performance due to the absence of PDMS.…”

In this paper, first, UV-curable vinyl-terminated hyperbranched polyester (VTDP) is synthetized via a two-step reaction. Then, mono-sulfhydryl terminated polydimethylsiloxane (PDMS-SH) is prepared via esterification reaction. Finally, cotton fabrics are immersed in mixtures of PDMS-SH, double-sulfhydryl terminated polydimethylsiloxane (HS-PDMS-SH), VTDP and hydrophobic fumed silica (HFS), and cross-linking polydimethylsiloxane with hydrophobic fumed silica (HCPDMS@HFS) fabrics are prepared by 35 s of UV irradiation. When the content of HFS is 2.0 wt%, the superhydrophobic HCPDMS@HFS fabrics with high water contact angle (158.5) as well as low sliding angle (6.8) are obtained. At the same time, HCPDMS@HFS fabrics can withstand sandpaper abrasion for 30 cycles and tape-peeling repetition for 100 times. They also exhibit excellent self-cleaning ability, chemical durability, thermal stability, and good recyclability.
