Trimethoxy(2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-octadecafluorodecyl)silane (CAS# 83048-65-1) has been used in the preparation of abrasion resistant super-antiwetting nylon surfaces. As an additive, Trimethoxy(2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-octadecafluorodecyl)silane is used to increase the hydrophobicity of the surfaces of carbon nanotube structures. | [Application]
1H,1H,2H,2H-Perfluorodecyltrimethoxysilane is a raw material in area of anti-reflective coating, release coating, soil-repellent coating.
Coating for electronic products.
It is used for self-cleaning of glass and other products. The low refractive index of fluorosilane can prevent the reflection of light from the substrate.
Hydrophobic and oleophobic treatment of glass or fiber surfaces.
For the preparation of wear-resistant super-moisture-resistant nylon surfaces.
As an additive, it is used to increase the hydrophobicity of the surface of the carbon nanotube structure. | [Mechanism of action]
The hardness of the coating decreased slightly with the addition of 1H,1H,2H,2H-Perfluorodecyltrimethoxysilane (PFTS), which is probably due to the steric hindrance of long perfluoroalkyl chains affecting the condensation of siloxanes and the reaction between epoxide ring (E) and primary amine (PA). The coated surface becomes hydrophobic with the increasing moral ratio of PFTS/PTMS. The increased hydrophobic property should be due to the increased groups of -CF2 and -CF3, which could reduce the surface energy of the coating. Moreover, the surface energy decreases with the addition of PFTS (C1-C5) since the PFTS tends to migrate towards the surface of the coating gradually and significantly improves the hydrophobicity of the coating. The additional amount of the DTDA and PFTS could help form a hard siloxane skeleton and stabilize the three-dimensional structure, which could benefit its anti-aging performance. Meanwhile, no apparent change in the appearance or color of the coatings was found, indicating a favorable weather resistance performance. PFTS have low-surface energy that can effectively tune the surface energy to achieve wettability changes between superILphilic and ILphobic[1-2]. | [References]
