“…Surface modification, which can be achieved by etching [24], chemical treatment [25,26], or physical treatment [27,28], provides the opportunities to tune optical, electrical, [29][30][31][32][33][34][35] and interfacial [36-38] material properties. Owing to the availability of reactive groups, mostly soft nucleophiles or electrophiles, most polymer surfaces can be readily modified through chemical grafting by simply exposing the material to an appropriate reagent(s) [1,[7][8][9]14,15,[17][18][19][20][21][22][39][40][41][42][43][44][45][46][47][48][49][50][51][52].…”

“…Surface modification techniques have been widely employed for improving textile functional performances, such as softness, dyeability, wettability, lubricity, anti-winkle and anti-microbial properties for decades [49,[63][64][65][66][67][68][69][70]. Surface modification techniques in textiles are divided into: chemical, mechanical, or combined methods.…”

“…This patent described the use of alkyl silane to modify the surface wetting properties of textiles [74]. Since then several methods have been reported for the application of silanes in textiles for surface modification [44,49]. A common technique used is the spraying technique due to its simplicity and high water contact angles upon treatment.…”

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.

“…In particular, the best effect is obtained by applying fluoro derivatives of organosilicon compounds, which combine unique properties of both components (Owen and Dvornic 2012). Among this group of compounds, the most frequently applied ones were fluorofunctional trichloro-and trialkoxysilanes (Leng et al 2009;Pipatchanchai and Srikulkit 2007;Textor and Mahltig 2010;Hayn et al 2011) as well as fluorosilyl amide (Evsyukova et al 2009(Evsyukova et al , 2011Ivanova and Zaretskaya 2011). On the other hand, classical polysiloxanes were used relatively rarely because of difficulties with their adhesiveness and durability of bonding to fibers.…”

Fabrication of superhydrophobic cotton fabrics by a simple chemical modification

et al. 2016

Hydrophobization of cotton fabrics was carried out with the use of bifunctional polysiloxanes with various contents of functional groups. Polysiloxanes contained in their structure groups capable of bonding to substrates (trialkoxysilyl or glycidyl ones) and fluoroalkyl groups showing surface activity. Two methods of surface modification were compared: (1) a one-step method via the chemical modification of fabrics with solutions of bifunctional polysiloxanes and (2) a two-step method-via preliminary modification of fabrics with silica sol followed by chemical modification with solutions of bifunctional polysiloxanes. The hydrophobicity was determined by measuring the water contact angle by drop profile tensiometry. Changes in the surface topography were examined by scanning electron microscopy. Superhydrophobic fabrics were obtained by a simple one-step method by the chemical modification in solutions of bifunctional polysiloxanes. The fabrics maintained their superhydrophobic properties even after multiple washings. The modification does not cause any changes visible to the naked eye, such as stiffening, color changes or a decrease in mechanical properties.

“…Non-wettable surfaces with high water contact angles (greater than 150°) and low tilting angle of drops, which are called superhydrophobic or ultrahydrophobic, have received remarkable attention in the recent years [1][2][3][4][5][6][7]. To achieve superhydrophobicity both appropriate surface roughness and low surface Energy are required.…”

A superhydrophobic surface with self-cleaning properties can be fabricated with a combination of both low surface energy and the proper surface roughness. In this paper, the possible effects of structural parameters of weft knitted fabrics were applied to produce surface roughness while a fluorocarbon compound was coated on the surface in order to generate low surface energy. In addition, to create dual surface roughness on the polyester fibers, chemical etching with alkaline hydrolysis and application of nanoparticles were investigated. The water repellency of the treated samples was evaluated by 3M, tilting angle and contact angle hysteresis.Comparison of a smooth polyester film and the knitted fabrics showed that various knitted structures and stitch densityhad a great effect on superhydrophobicity. Polyester alkaline hydrolysis efficiently roughened the surface and after the fluorocarbon coating, remarkable improvement in repellent properties was observed. Thus, there was no necessity to use nanoparticles.
