“…Under appropriate pressure, the oil can be completely separated from the oil-water mixture through the film. Tseng et al [18] and Xu et al [19] prepared a graphene layer on the surface of polyimide film using the biological template and laser etching method. By adjusting the process parameters of laser etching, good superhydrophobicity of the polymer film could be achieved, which had important application prospects in anti-sweat and serum adhesion.…”

In order to improve the preparation efficiency, quality stability, and large-area preparation of superhydrophobic thin films, a roll-to-roll continuous micro–nano imprinting method for the efficient preparation of superhydrophobic polymer films is proposed. A wear-resistant mold roller with hierarchical microstructure is prepared by wire electrical discharge machining (WEDM). The rheological filling model is constructed for revealing the forming mechanism of superhydrophobic polymer films during continuous micro/nano imprinting. The effects of imprinting temperature, rolling speed and the surface texture size of the template on the surface texture formation rate of polymer films are analyzed. The experimental results show that, compared with other process methods, the template processed by WEDM shows excellent wear resistance. Moreover, the optimal micro/nano imprinting parameters are the mold temperature of 190 °C (corresponding film temperature of 85 ± 5 °C), rolling speed of 3 rpm and roller gap of 0.1 mm. The maximum contact angle of the polymer film is 154°. In addition, the superhydrophobic polymer thin film has been proven to have good self-cleaning and anti-icing performance.

“…The strongest material known is graphene, which has a stable structure, high toughness, large specific surface area, and special lamellar structure of multilayer graphene with excellent self-lubricating properties [12,13]. It is due to the excellent physical and chemical properties of graphene that it has been used in semiconductors [14,15], energy [16,17], functional coating [18], composite materials [19], aerospace [20], and other fields [21,22]. Consequently, graphene material possesses excellent physical and chemical properties as a tool coating material in the tool industry and has important practical significance and practical value [23][24][25].…”

The preparation technology of graphene-based coatings on cobalt-based cemented carbides and the friction properties of graphene-based coatings were researched. Based on cooling rate, growth temperature, and methane flow rate, Raman spectroscopy was used to evaluate the influence of chemical vapor deposition (CVD) on graphene-based coatings. The results show that at the growth temperature of 1000 °C, the cooling rate of 15 °C/min and methane flow rate of 10 sccm are more favorable for the growth of pure graphene coating with fewer layers on a cemented carbide surface. As methane flow boosts, the number of graphene layers increases and amorphous carbon is generated. The resulting tribological properties demonstrate that the friction coefficient of graphene-based coatings decreases as the friction load increases. The above results indicate that the graphene-based coating on a cemented carbide surface can be prepared by regulating its composition and defects through technological parameters, and it is viable to use graphene-based coating as anti-wear coating for cutting tools. The results provide a reference for the preparation and properties of cemented carbide surface graphene.
