“…The mold with lower surface energy tend to increase the freezing delay time and degree of supercooling due to a smaller contact area with the aqueous suspension. This will result in smaller ice nuclei uniformly formed in the whole suspension [31]. In addition, it is understandable that the suspension with low BC concentration tends to obtain a highly porous aerogel.…”

Bacterial cellulose (BC) aerogel has great potential in treating oil spill and organic pollutant. However, its inherent hydrophilicity and poor rigidity limit its practical application and recyclability. In this study, elastically compressible and high oil-absorbing aerogels were developed by freeze-drying aqueous suspensions with appropriate BC concentrations, followed by a chemical vapor deposition of methyltrimethoxysilane with ammonia as catalyst. The modi ed aerogel shows high water contact angle of 142° and enhanced compression resistance. The effect of BC concentration on the adsorption capacity and recyclability of aerogel has been investigated. The results show that the aerogel prepared with 0.3 wt% BC exhibits simultaneously high absorption capacity (121.8-284.1 g/g) and excellent recyclability. Futhermore, the aerogel could also separate chloroform-water mixture by gravity-driven ltration, giving the separation e ciency of 96.7 %. Therefore, this economical green aerogel provides a feasible strategy for solving oil leakage in industry.

“…Water control at extreme states (i.e., superhydrophobicity or superhydrophilicity [1]), enables a palette of functionalities, such as self-cleaning, antifogging [2,3], anti-icing [4,5], anti-biofouling [6], high-binding [7], antibacterial activity [8][9][10], chemical shielding [11], drag reduction [12,13], etc. Wetting control has been achieved in a wide range of materials, such as polymers [14,15], metals [16,17], alloys [18], and ceramics using several fabrication methods [19][20][21][22][23].…”

Hydrophobicity and superhydrophobicity with self-cleaning properties are well-known characteristics of several natural surfaces, such as the leaves of the sacred lotus plant (Nelumbo nucifera). To achieve a superhydrophobic state, micro- and nanometer scale topography should be realized on a low surface energy material, or a low surface energy coating should be deposited on top of the micro-nano topography if the material is inherently hydrophilic. Tailoring the surface chemistry and topography to control the wetting properties between extreme wetting states enables a palette of functionalities, such as self-cleaning, antifogging, anti-biofouling etc. A variety of surface topographies have been realized in polymers, ceramics, and metals. Metallic surfaces are particularly important in several engineering applications (e.g., naval, aircrafts, buildings, automobile) and their transformation to superhydrophobic can provide additional functionalities, such as corrosion protection, drag reduction, and anti-icing properties. This review paper focuses on the recent advances on superhydrophobic metals and alloys which can be applicable in real life applications and aims to provide an overview of the most promising methods to achieve sustainable superhydrophobicity.

“…However, moisture condensed in nanostructures and finally anchored the ice in high humidity and sub-zero condition, leading to the result that the ice adhesion strength increased. More seriously, the ice accumulated on the surface easily after the de-icing process destroying the textures [ 13 , 14 ]. Combined with thermal methods, the superhydrophobic/electrothermal method was another effective way to prohibit ice formation [ 15 ].…”

A convenient, environment-friendly, and cost-effective method to keep anti-icing for a long time was highly desirable. Slippery lubricant layers were regarded to be effective and promising for anti-icing on different surfaces, but the drought-out of lubricants and the possible detriments to the environment were inevitable. By combining super-high molecular weight sodium polyacrylate (H-PAAS) with polyolefin through a one-pot method, a self-sustainable lubricating layer with extremely low ice adhesion of un-freezable water hydrogel was achieved at subzero conditions. The lubricant hydrogel layer could auto-spread and cover the surface of polyolefin after encountering supercooled water, frost, or ice. Due to the reduction of storage modulus in the interface, the ice adhesion of the specimen surfaces was far below 20 kPa, varying from 5.13 kPa to 18.95 kPa. Furthermore, the surfaces could preserve the fairly low adhesion after icing/de-icing cycles for over 15 times and thus exhibited sustainable durability. More importantly, this method could be introducing to various polymers and is of great promise for practical applications.
