“…For the oxidized wafer, the O 1s and Si 2p peaks correspond to the wafer whereas the carbon (C 1s) is attributed to adsorbed contaminants. 44, 45 Following grafting, the Si 2p content decreased and the C 1s content increased. The C 1s peak was deconvoluted into two peaks centered at 284.5 eV (C–C and C–Si) and 286.4 eV (C–O), with this latter peak unique to PEO 28 (Fig.…”

Silicones with improved water-driven surface hydrophilicity and anti-biofouling behavior were achieved when bulk-modified with poly(ethylene oxide) (PEO) –silane amphiphiles of varying siloxane tether length: α-(EtO)3Si-(CH2)2-oligodimethylsiloxanem-block-poly(ethylene oxide)8-OCH3 (m = 0, 4, 13, 17, 24, and 30). A PEO8-silane [α-(EtO)3Si-(CH2)3-PEO8-OCH3] served as a conventional PEO-silane control. To examine anti-biofouling behavior in the absence versus presence of water-driven surface restructuring, the amphiphiles and control were surface-grafted onto silicon wafers and used to bulk-modify a medical-grade silicone, respectively. While the surface-grafted PEO-control exhibited superior protein resistance, it failed to appreciably restructure to the surface-water interface of bulk-modified silicone and thus led to poor protein resistance. In contrast, the PEO-silane amphiphiles, while less protein-resistant when surface-grafted onto silicon wafers, rapidly and substantially restructured in bulk-modified silicone, exhibiting superior hydrophilicity and protein resistance. A reduction of biofilm for several strains of bacteria and a fungus was observed for silicones modified with PEO-silane amphiphiles. Longer siloxane tethers maintained surface restructuring and protein resistance while displaying the added benefit of increased transparency.

“…The wide peak centred around 285 eV for the specimens exposed to CTAB could be related to organic C-C bonds (285.0) with contributions from the C-N bond. A binding energy of 286.5 eV has been reported for the C-N bond of quaternary ammonium compounds [30]. Surface accumulation of carbon, originating from traces of dissolved C in the electrode material, may also contribute, since a peak also is observed for the "No inhibitor" specimen (284.5 eV).…”

“…These molecules have to be used in organic solvents such as toluene, acetone, methanol, ethanol, and the like. The silanol creates a bond Si-O-Si with the silica substrate [14] while allyl or vinyl generates Si-O-C (or Si-C) bond [34] and the azide groups produce Si-N bond [44].…”
