Although silicones possess many useful properties as biomaterials, their hydrophobicity can be problematic. To a degree, this issue can be addressed by surface modification with hydrophilic polymers such as poly(ethylene glycol), but the resulting structures are usually not conducive to cell growth. In the present work, we describe the synthesis and characterization of covalently linked hyaluronic...
Monofunctional poly(ethylene oxide) polymers of molecular weight (MW) 350, 750, and 2000, respectively, were modified with Si(OEt) 3 groups. These polymers underwent classic condensation cure with hydroxy-terminated silicone polymers and Si(OEt) 4 to give composites with poly(ethylene oxide) (PEO) rich surfaces under aqueous conditions, as shown by contact angle and XPS data. The hydrophobicity...
