“…The formation of short 1D-SNF (~100 nm) is already reported after few minutes, while longer reaction times led to longer 1D-SNF (figure 4). Some studies suggest that the length of the 1D-SNF increases fast initially but levels off at elongated reaction times [9,13,56]. The thickness of the coating grows correspondingly.…”

“…Probably, the most outstanding property of these coatings is their extreme water repellency [7][8][9][11][12][13][14] with contact angles up to 180° being measured [7]. Therefore, the investigation of the superhydrophobicity of 1D-SNF coatings either aiming at commercial applications or with respect to the theoretical understanding is the central part of many studies .…”

A decade ago one-dimensional silicone nanofilaments (1D-SNF) such as fibres and wires were described for the first time. Since then, the exploration of 1D-SNF has led to remarkable advancements with respect to material science and surface science: one-, two-and three-dimensional nanostructures of silicone were unknown before. The discovery of silicone nanostructures marks a turning point in the research on the silicone material at the nanoscale. Coatings made of 1D-SNF are among the most superhydrophobic surfaces known today. They are free of fluorine, can be applied to a large range of technologically important materials and their properties can be modified chemically. This opens the way to many interesting applications such as water harvesting, superoleophobicity, separation of oil and water, patterned wettability and storage and manipulation of data on a surface. Because of their high surface area, coatings consisting of 1D-SNF are used for protein adsorption experiments and as carrier systems for catalytically active nanopartides. This paper reviews the current knowledge relating to the broad development of 1D-SNF technologies. Common preparation and coating techniques are presented along with a comparison and discussion of the published coating parameters to provide an insight on how these affect the topography of the 1D-SNF or coating. The proposed mechanisms of growth are presented, and their potentials and shortcomings are discussed. We introduce all explored applications and finally identify future prospects and potentials of 1D-SNF with respect to applications in material science and surface science.

“…They demonstrated that the treated fabric has remarkable durability against repeated machine washes and excellent stain resistance (Figure 4b,c). Properties imparted to textiles using silane solution include water repellence, soil/dirt resistance, wrinkle resistance, anti-bacteria, anti-static, UV-protection, flame retardation, and improvement of dyeability, among others [21,49,51,65,77]. The main problem, however, is that most of these methods do not offer permanent modification and the fabric tends to lose the new property upon laundering or use.…”

Abstract:Modifying the chemistry of a surface has been widely used to influence interfacial properties of a material or nature of interaction between two materials. This article provides an overview on the role of polyfunctional molecules, specifically silanes, in surface modification of polar surfaces (bearing soft nucleophiles). An emphasis on the mechanism of the reaction in the presence of adsorbed water, where the modifying reagents are hydrolysable, is discussed. To highlight the complexity of the reaction, modification of paper with trichlorosilanes is highlighted. Preparation of hydrophobic cellulosic paper, and structure-property relations under different treatment conditions is used to highlight that a monolayer is not always formed during the surface modification. Gel-formation via step-growth polymerization suggests that at the right monomer:adsorbed water ratio, a monolayer will not form but rather self-assembly driven particle formation will occur leading to a textured surface. The review highlights recent work indicating that the focus on monolayer formation, is at the very least, not always the case but gel formation, with concomitant self-assembly, might be the culprit in understanding challenges associated with the use of polyfunctional molecules in surface modification.

Multiscale structures of biotic materials exhibiting natural integration provide a model for the development of functional surfaces with special wettability. Inspired by nature, for example, by the lotus leaf and butterfly wings that show excellent superhydrophobicity, scientists have recently fabricated a variety of biomimetic superhydrophobic membranes through various smart and easy routes. After a brief description of natural superhydrophobic surfaces and the structural and functional biomimetic surfaces, we present the design and fabrication methods of these bio‐inspired superhydrophobic fibrous membranes. The main focus is the overview of the polymeric materials used to fabricate the superhydrophobic fibrous membranes at nano‐ or microscales and the chemical modifications that led to superhydrophobicity of as‐prepared polymeric and inorganic fibrous membranes. Later, we describe the induced superhydrophobicity in common textile fibrous surfaces. In addition, we highlight some potential applications associated with these remarkable biomimetic surfaces.
