Abstract: | In this paper, novel fluorinated silane compound was prepared by adding hydroxyl terminated Fluorolink D10H oligomer to 3-(triethoxysilyl)propylsuccinicanhydride.
The obtained silane system was independently composed with 3-Aminopropyltrimethoxysilane, 3-Glycidyloxypropyltrimethoxysilane
and 3-Glycidyloxypropyltriethoxysilane and, then the prepared coating solutions were applied to glass surface by spin-coating
method. The chemical bonding between groups in system was investigated by Fourier Transform Infrared Spectroscopy analyses.
The elemental composition of coatings was determined using Energy Dispersive X-ray Spectroscopy analyses. Its structure and
surface properties were analyzed by scanning electron microscopy, atomic force microscopy, contact angle measurement and Ultraviolet–visible
Absorption Spectroscopy. The amounts of fluorine on the coatings prepared with GF20-D10H-AMMO, GF20-D10H-GLYEO and GF20-D10H-GLYMO
are 31, 32 and 34% at, respectively. Transparent coatings with smooth surface and uniform thickness were observed. The coatings
had nanoscale roughness. The contact angles of coatings for water ranged from 88 to 107o, and that of n-hexadecane ranged from 53 to 60o. |
