“…Finally, another important aspect related to the sol-gel technology is the high versatility to accept a wide variety of biocide compounds which are perfectly embedded in the silica matrix. In another work, Mahltig et al [92] have reported the preparation of modified silica coatings which contain embedded biocide materials. More specifically, an exhaustive study about silica layers embedded silver, silver salts and biocidal ammonium quaternary salts is presented as a function of three specific parameters such as antimicrobial efficacy, wash-out and long-term behavior.…”

This review reports the implementation of novel nanostructured functional coatings by using different surface engineering techniques based on wet chemistry. In the first section, the theoretical fundaments of three techniques such as sol-gel process, layer-by-layer (LbL) assembly and electrospinning will be briefly described. In the second section, selected applications in different potential fields will be presented gathering relevant properties such as superhydrophobicity, biocide behavior or applications in the field of optical fiber sensors.

“…The bacterial reduction % also increases with increase in silver content as well. Mahltig et al (2004) investigated antibacterial effect by embedding the biocides in silica coatings. Biocides used in this study were silver nitrate, colloidal Ag, (cetyltrimethylammoniumbromide) CTAB, and octenidine.…”

“…Biocides used in this study were silver nitrate, colloidal Ag, (cetyltrimethylammoniumbromide) CTAB, and octenidine. Silica sol solution was prepared from tetraethoxysilane (TEOS) and 3-glycidyloxypropyltriethoxysilane (GOPTS) [50]. Properties such as antibacterial efficacy wash-out and long-term behavior were analyzed.…”

“…Such a property is shown by silicone-organic coatings made of a sol synthesized from vinyltriethoxysilane by the sol-gel method. Moreover, such coatings constitute matrices to which one can durably incorporate inorganic or organic functional particles with specified properties and in this way obtain expected functionalization of textile fabrics, such as bioactivity, [1][2][3][4][5][6] water resistance, [7][8][9] barrier property against UV radiation, 10,11 optimized performance durability-resistance to abrasion or pilling formation. [12][13][14][15][16] The basic condition of the application of a thin coating based on SiO 2 , made by the sol-gel method for various so-called nano-coating finishes of textile fabrics, is its stable adhesion to the surface of fiber/fabric.…”

This paper presents the effect of pretreatment of polyamide (PA6) nonwoven with corona discharge on the stability of the adhesion of thin hydrophobic silicone-organic coating based on vinyltriethoxysilane, made by the sol-gel method. This pretreatment with corona discharge causes a change in the physicochemical properties of the PA6 fiber surface. These changes include, among others, an increase in the fiber surface roughness, wettability, and surface free energy. At the same time, XPS and EDS investigations have shown an increase in the degree of oxidation and the formation of functional polar groups on the fiber surface (C-O-, C-OH, and O=C-O-). As a result of the changes in the surface properties of pretreated PA6 fibers, a higher degree of the sol deposition was obtained compared with that for untreated nonwoven surface. The assessment of the stability of the adhesion of thin hydrophobic coating to the fiber surface was carried out on the basis of changes in the content of silica deposited on fibers and the kinetics of water contact angle after washing and abrasion processes. In the end, the PA6 nonwoven, pretreated with corona discharge, shows a higher stability of the adherence of the thin silicone-organic coating and a higher degree of hydrophobicity than the untreated nonwoven.
