“…Therefore, the preparation of superhydrophobic surface must consider two decisive factors: the surface roughness of the material and the surface energy of the material. Superhydrophobic materials have been used in anti-icing [5][6][7], anti-corrosion [8][9][10], self-cleaning [11,12], oil-water separation [13][14][15] and other fields. For the metal surface, the coating prepared by the superhydrophobic material can effectively reduce the corrosion rate or prolong the icing time.…”

In this paper, a preparation method of superhydrophobic composites of oxidized multi-walled carbon nanotubes modified by stearic acid (SA) is proposed. Hydroxylated multi-walled carbon nanotubes (HMWCNT) were obtained by oxidizing multi-walled carbon nanotubes with potassium dichromate to give them hydroxyl groups on the surface. Subsequently, the carboxyl group in the SA molecule was esterified with the hydroxyl group on the hydroxylated multi-walled carbon nanotubes. SA molecules were grafted onto the surface of multi-walled carbon nanotubes. SA modified oxidized multi-walled carbon nanotubes (SMWCNT) superhydrophobic composites were obtained. The results show that the water contact angle (WCA) of superhydrophobic composites can reach up to 174 °. At the same time, the modified nanocomposites have good anti-icing and corrosion resistance. After low temperature delayed freezing test, the freezing extension time of the nanocomposite film is 30 times that of the smooth surface. Under strong acid and alkali conditions, the superhydrophobic nanocomposites still maintain good superhydrophobicity. The nanocomposites may have potential applications in the preparation of large-scale superhydrophobic coatings.

“…The superhydrophobic surfaces (SHSs) inspired by lotus leaves have emerged as a focal point in the realm of anti-icing materials research. − The micronano structures make the droplet present Cassie state on SHSs, which hinders the heat transfer between the droplet and SHSs, thus prolonging the icing time. Meanwhile, the low sliding angle of the superhydrophobic surface makes it easy for droplets to slide off the surface before freezing, causing a reduction in the icing possibility.…”

Transparent photothermal coatings are increasingly important in various fields, including solar panels, front windshields, and aircraft windows, to prevent icing, which would otherwise affect their efficiency and safety. However, past research on photothermal materials has overly focused on achieving high photothermal performance at the expense of basic transparency. Meanwhile, superhydrophobic surfaces and slippery liquid-infused porous surfaces have been found to have poor durability as anti-icing materials, thereby limiting their practical applications. In this work, we prepared a liquid-like anti/deicing coating with excellent transparency by utilizing polybutadiene (PB), sulfhydryl-functionalized polyhedral oligomeric silsesquioxane (POSS), and hydroxyl-terminated polydimethylsiloxane (PDMS) to construct a semi-interpenetrating cross-linked network and adding nigrosin dye with full spectrum absorption and benzotriazole (BTA) with UV-selective absorption as photothermal components. Liquid-like properties enable extremely low surface ice adhesion (∼13 kPa). Compared with bare glass, the coating freezes three times longer, greatly improving the anti-icing performance. Furthermore, the coating can have excellent photothermal performance while maintaining high transparency. This unique combination of properties facilitates its application of the coating in some anti/deicing scenarios where transparency is required, and the excellent durability and antifouling properties make it possible for long-term use. Such a coating can be manufactured on metal, plastic, wood, and other substrates by a simple drop coating and UV curing method.

“…The surface of the lotus leaf is also known as a superhydrophobic surface [5]. Superhydrophobic surfaces have a broad application prospect due to their self-cleaning properties [6], oil water separation [7], anti-corrosion [5,8], antifreezing [9], and ice protection [10]. In recent years, researchers have developed and implemented this bionic superhydrophobic surface in various ways [11,12], which has exhibited excellent superhydrophobicity.…”

“…The biggest advantage of the impregnation method for preparing superhydrophobic surfaces is its simplicity. Currently, there are two commonly used strategies: (1) dispersing hydrophobic nanoparticles into suitable organic systems, and then directly impregnating the porous matrix material to form a stable superhydrophobic surface [9,29]; (2) micro and nano particles with a certain morphology and structures are dispersed into an organic solvent, and a composite structure is rstly constructed on the surface of the matrix material through a impregnation process [30], and then hydrophobically modi ed. At present, some documents have constructed superhydrophobic surfaces by using a high concentration of solution coating, which has changed the original morphology and characteristics of paper and cloth through impregnation.…”

Superhydrophobic surfaces have been extensively studied for their self-cleaning properties. However, most of the constructed superhydrophobic surfaces have problems of changing the surface morphology and color of paper/cloth. An extremely dilute superhydrophobic solution was prepared by hybrid assembly of aminated nano SiO2 and high fluorine epoxy polymer P(FOEMA-r-GMA). The preparation of superhydrophobic cotton (SHC) and superhydrophobic book paper (SHBP) were studied through the optimal construction conditions of solution impregnation method. The optimal construction conditions for SHC were as follows: the concentration of fluorinated epoxy polymer was 3 mg/mL, the soaking time was 5 hours, the drying time was 8 hours, and the drying temperature was 120oC. The maximum WCA is 158 ° ± 3o, and the minimum WRA is 4o ± 3o. SHC surface had good hydrophobic effect, acid and alkali resistance, self-cleaning effect, and its surface morphology remains basically unchanged. SHC could be used for oil water separation with a maximum oil water separation rate of 98.4%. The optimal construction conditions for SHBP were: the concentration of fluorinated epoxy polymer was 3 mg/mL, the soaking time was 9 hours, the drying time was 6 hours, the maximum WCA was 155o ± 3o, and the minimum WRA was 6o ± 1o. The hydrophobicity of SHBP was significantly improved, it would selective adsorbing oil from the oil water mixture and slightly reduce its smoothness.
