“…Other materials have also been explored to produce superamphiphobic surface coatings with exceptional properties such as copper acetate, silver nitrate, liquid marbles (LMs), and multiwalled carbon nanotubes. [41,97,98,99] Yang et al explored the production of rough structures with fluorinated materials by spraying a copper fluorooctanoate suspension created by the reaction of copper acetate and perfluorooctanoic acid (PFOA) in water. The reaction of copper acetate and PFOA, specifically, the coordination of Cu 2+ ions with CF 3 (CF 2 ) 6 COO − ions to form copper perfluorooctanoate, was critical to the formation of this surface.…”

“…Silica synthesis using CNTs/CNFs was previously studied in sol–gel processes. Zhang et al reported that polysiloxane was deposited on multiwalled CNTs (MWCNTs) via hydrolysis of silane precursors and formed silica nanotubes showed superamphiphobic property. − In their study, MWCNTs was treated with the mixture of H 2 SO 4 /HNO 3 to remove metal impurities and NH 3 was used to proceed hydrolysis of silane precursors. In our study, CNFs containing no metal catalysts were used so that the effect of impurities with/without acid treatment can be ignored.…”

Coating of Silica Nanolayers on Carbon Nanofibers via the Precursor Accumulation Method

et al. 2020

Surface modification of nanocarbons, for example, by coating with oxide nanolayers, is a research topic of significant interest because of the drastic changes in the physicochemical properties of the modified nanocarbons. One simple method of creating these oxide nanolayer coatings on nanocarbons is the precursor accumulation (PA) technique, which entails the following: (1) a precursor solution is added dropwise onto nanocarbon powder; (2) the solvent is dried, leaving the accumulated precursor on the nanocarbon surface; and (3) hydrolysis or decomposition of the precursor in air leads to the formation of oxide nanolayers on the nanocarbons. In this study, tetraethoxysilane (TEOS) was used as a precursor for coating silica nanolayers onto carbon nanofibers (CNFs). TEOS is so stable that it hardly undergoes hydrolysis on the surface of pristine CNFs. By treating CNFs with H 2 SO 4 / HNO 3 , acidic functional groups were introduced onto the CNF surfaces. Silica nanolayers were successfully synthesized on these acid-treated CNFs via PA coating because the acidic functional groups catalyzed the hydrolysis of TEOS accumulated on the CNF surfaces. Scanning transmission electron microscopy indicated that the thickness of silica layer is approximately several nanometers. Pore size distribution analysis for the silica nanolayer suggested the presence of nanopores with 3−5 nm. The TEOS molecules could have accessed the functional groups through the nanopore; therefore, the number of silica nanolayers formed increased with the number of PA coatings. Finally, we compared the PA coating with conventional sol−gel and atomic layer deposition techniques.

“…However, previous studies have mainly focused on the surface of 2D materials, [ 5 ] and amphiphobic sponges have rarely been investigated. [ 6–8 ] The term amphiphobicity, which comprises both superhydrophobicity and oleophobicity, refers to the ability to repel oil and water [ 9–11 ] and has been widely used in the fields of self‐cleaning, antipollution activities, anti‐icing operations, and low friction applications. [ 12,13 ] Generally, the structure and chemical composition of materials are key factors in achieving a low surface energy.…”

The fabrication of amphiphobic materials requires a precise and complicated design, especially for 3D porous materials, and amphiphobic sponges have rarely been investigated. This paper describes the synthesis of a superhydrophobic and oleophobic silicone sponge (SS‐F) by simply building hierarchical structures, that is, introducing a secondary structure on the pore walls of a hydrophobic and oleophilic silicone sponge. This simple and efficient synthesis method is based on the thiol–ene click reaction. The uniform structure, composition, and hierarchical structures of SS‐F are confirmed. The results of the analyses show that the secondary microstructure improves liquid repellency, while the rough and porous surface design ensures durability. Thus, SS‐F exhibits good stability, and the amphiphobicity of the surface could withstand scalpel cutting, cyclic compression, extreme temperatures of 250 and −196 °C for 5 h, and long‐term storage in an ambient environment. Both its outer and inner surfaces show superhydrophobicity and oleophobicity, which restrict the ability of the adsorption of liquids, enabling its use in oil and water. The introduction of hierarchical structures paves a way for preparing other 3D porous materials.
