As an environmentally friendly aerogel with outstanding performances, the improvement of mechanical properties is urgently required for cellulose aerogel development. In this study, a cellulose aerogel with good mechanical properties was successfully fabricated using nanocrystalline cellulose (NCC) as reinforcer. Characterization results demonstrated that NCC was embedded well into the cellulose aerogel. Tests and evaluation showed that the compressive modulus of the NCC reinforced cellulose aerogel was significantly improved, about 6 times higher than that of the pure cellulose aerogel.Furthermore, after modification with trimethylchlorosilane via a cold plasma treatment, the NCC reinforced aerogel became hydrophobic but its oleophilic property remained. This aerogel showed good adsorption capacity, reached saturation rapidly and possessed good reusability. Reinforced mechanical properties with NCC make this cellulose aerogel a very promising material for highly efficient separation and extraction of organic pollutants and oils from water.

“…[62][63][64] For example, Wang et al 64 fabricated a robust superhydrophobic/superoleophilic carbon nanotube (CNT)/poly(dimethylsiloxane) (PDMS)-coated PU foam for the continuous absorption of oils and organic solvents from water surfaces. When applied in conjunction with a vacuum system, this sponge could separate great amounts of oils up to 35,000 times its own weight from water in a one-step process [ Fig.…”

With the development of society, oil pollution has become more and more serious, it is becoming a global issue to separate oil and water mixture. Currently, a variety of functional materials have been successfully prepared for oil/water separation. Among them, polyurethane is an attractive candidate due to its low cost, wear-resistance and excellent mechanical properties. This report summarizes the design strategy of polyurethane-based materials and their applications in oil/ water separation. The progress made so far will guide further development of polyurethane-based materials for oil/water separation.

“…Because of the super hydrophobic surface in the super hydrophobic surface, refers to the water contact angle greater than 150 degrees, the rolling angle of less than 10 degrees of surface. Because of its many applications such as cleaning [3] [4] , corrosion resistant [5] [6] , anti icing [7] , oil-water separation [8] and so on, more and more attention has been paid to it. Many studies have revealed that the super hydrophobic surface is produced by proper surface roughness and low surface energy [9] , for example，ａ large number of artificial superhydrophobic surfaces can be prepared by the method of layer by layer deposition [10] , on the basis of template [11] , Photolithography [12] , sol-gel method [13] .…”

the insulator is a kind of important electric components, because it plays a role in electrical insulation and plays a supporting role in mechanical, power system and even the development of the whole society to a higher degree of dependence on the performance of insulators, the requirements are also rising. However, in recent years, China's domestic air pollution is serious, the weather conditions are complex, the icing flashover phenomenon has become a serious performance of insulator safety accidents. However, the proposed super hydrophobic materials in this paper, not only the anti icing flashover performance is better than the commonly used coating, and preparation process is sample, high performance, and low cost, which is expected to become a substitute for insulator coating now.the super hydrophobic coating is considered to be one of the important methods to solve the problem of flashover electrical equipment, so the study of high hydrophobicity flashover, super hydrophobic coating with high performance, simple process, low cost plays an important role in electrical equipment and power industry. In this paper, we will use a kind of method which is more powerful, graphene was prepared by electrochemical stripping and poly-two methyl siloxane in a certain proportion to prepare superhydrophobic surface. In this paper, the preparation of superhydrophobic surface, not only has excellent self-cleaning performance, but also has a very low corrosion current density. It is surprising that the superhydrophobic surface prepared by this method has good mechanical stability, and its surface can maintain the super hydrophobicity after the strong impact of the outside world. The method mentioned in this paper is not only capable of preparing a set of super hydrophobic surface self cleaning,mechanical stability is stable as a whole, it also provides a new idea for anti icing flashover of electrical equipment.Key words: Superhydrophobic Coating; Graphene; Insulator; Corrosion; Resistance IntroductionWith the development of the electric power industry and the gradual improvement of the voltage level, the electrical equipment is playing a more and more important role in people's daily production and life. Of which the insulator is an important part of power system, however, the phenomenon of icing flashover has a great influence on the mechanical and electrical properties of insulators, which will threaten the stability and security of power system operation, resulting in huge economic losses. Take snow disaster in South China in 2008 as an example, the ice coating accidents spread to 13 provinces, State Grid economic losses in the accident up to 10 billion 450 million Yuan, and in daily life, line trip, outage accidents also occur caused by icing [1] , it causes a great impact on people's life. Therefore, it has become one of the most urgent problems to solve the problem of icing flashover. However, there are still a lot of defects in the deicing and anti icing methods currently used, and the efficiency is low a...
