Preparation and surface properties of silica-gel coating films containing branched-polyfluoroalkylsilane

Preparation of Water-Repellent Glass by Sol–Gel Process Using Perfluoroalkylsilane and Tetraethoxysilane

“…[1] and [2], respectively. The polycondensation reaction of hydrolyzed TEOS and PFAS on glass substrate can be described as in Eq.…”

“…Various studies have been done recently for enhancing the performance and expanding the applicable range of inorganic materials such as glass, ceramics, and metals by treating the inorganic materials at their surface with various surface-treating agents for improving surface properties (1)(2)(3)(4)(5)(6)(7). Perfluoroalkylsilane has been proposed and used for forming hydrophobic water-repellent films on the surfaces of various materials (1,2,(8)(9)(10)(11).…”

“…Perfluoroalkylsilane has been proposed and used for forming hydrophobic water-repellent films on the surfaces of various materials (1,2,(8)(9)(10)(11). Water-repellent coatings capable of repelling water applied thereto have attracted much attention because of their 1 To whom correspondence should be addressed.…”

Preparation and characterization of thermosensitive polymers grafted onto silica-coated iron oxide nanoparticles

“…The core-shell structure of SiO 2 /Fe 3 O 4 nanoparticles is shown as a dark dot with diameter 6 nm of Fe 3 O 4 and an asymmetric SiO 2 shell along the edges of the magnetic core. [23][24][25]. From these absorption bands, it is clearly known that SiO 2 was successfully covered onto the surface of the Fe 3 O 4 nanoparticles.…”

Template-assisted encapsulation of fluorinated silanes in silica films for sustained hydrophobic–oleophobic functionality

“…All of these systems suffer from inherent mechanical weakness which results in significant loss of functionality when subjected to wear. One common approach to attempt to mitigate such a loss of functionality due to mechanical damage is to apply hydrophobic-oleophobic layers by co-condensation of fluorosilanes with silicon alkoxides, but this approach usually results in a solid-air interface layer that is enriched in fluorinated moieties due to the thermodynamic drive of these components to migrate to low-surface energy interfaces [1][2][3][4]. Once this surface-enriched layer is removed, such as by mechanical abrasion, these coatings are also much less functional.…”
