In this work, linear amphiphilic PEG-silanes were utilized to prepare surface-grafted and bulk crosslinked silicone coatings with enhanced anti-fouling behavior.  The PEG-silanes contain a flexible siloxane tether of varying length and have the general formula: (EtO)3Si(CH2)2-oligodimethylsiloxane-block-(CH2CH2O)8-OCH3.  The flexible siloxane tether yields a PEG-silane which is amphiphilic and may enhance the molecular mobility of the PEG segment.  The reduced adhesion of blood proteins, whole blood and marine bacteria is related to the structure of the PEG-silane.
