Terminal silanization of perfluoropolyether, polydimethylsiloxane, their block polymer and the self-assembled films on plasma-treated silicon surfaces

Omniphobic Etched Aluminum Surfaces with Anti-Icing Ability

“…Characteristic absorption peaks of CF 2 and CF 3 groups, corresponding to the stretching vibration of C−F bonds, were observed between 1150 and 1200 cm −1 . 24 The peak at 1006 cm −1 can be assigned to the C−O−C ether bond. These characteristic bands were in agreement with those of pure PFPE and confirmed the presence of PFPE molecules on the surface of the rough aluminum substrate.…”

“…ATR-FTIR spectra of a pristine aluminum substrate and a PFPE film grafted onto a rough aluminum substrate are shown in Figure a. Characteristic absorption peaks of CF 2 and CF 3 groups, corresponding to the stretching vibration of C–F bonds, were observed between 1150 and 1200 cm –1 . The peak at 1006 cm –1 can be assigned to the C–O–C ether bond.…”

“…Omniphobic surfaces with covalently anchored perfluoropolyethers (PFPEs), able to repel any type of liquid, including water droplets, appear to be excellent candidates to address the abovementioned issues . Indeed, the use of PFPEs has been investigated after anchoring to smooth surfaces , or forming hybrid sol–gel coatings. , However, a direct covalent anchoring of PFPE molecules on tailor-made nanostructured surfaces is still unexplored.…”
