Fluoroalkylsilanes with Embedded Functional Groups as Building Blocks for Environmentally Safer Self-Assembled Monolayers


Abstract

The fabrication of silane-based fluorinated self-assembled
monolayers (FSAMs) on different substrates
was carried out making use of fluoroalkylsilanes (FAS):
containing an embedded
amide and a sulfonamide group, respectively, between the short
perfluoroalkyl chain (RF with C < 6) and the syloxanic moiety.


Description of Projectidea

The fabrication of silane-based fluorinated self-assembled
monolayers (FSAMs) on different substrates
was carried out making use of fluoroalkylsilanes (FAS):
containing an embedded
amide and a sulfonamide group, respectively, between the short
perfluoroalkyl chain (RF with C < 6) and the syloxanic moiety. The
obtained FSAM-modified/systems ca be characterized by X-ray
photoelectron spectroscopy (XPS), contact angle (CA), surface energy
measurements, and electrochemical impedance spectroscopy (EIS)
The presence of the -NHCO-; and -NHSO2- groups have a different mode of action and, despite the short perfluoroalkyl chain, the
system presents a CA and surface energy typical of amphiphobic materials. These properties
can be exploited in a variety of applications, such as self-cleaning, anti-fouling, and anti-fingerprint coatings, and in advanced
microelectronic components.
