Controlled morphology PEO-silicone composites have protein rejecting surfaces

Crosslinking density of silicone and mono-and difunctional PEO of different molecular weight were analyzed. It was found that morphological control of polyethylene oxides-(PEO)-silicone composites possessed proteins rejecting properties. Monofunctional and bifunctional and bifunctional PEO (R=(EtO) 3Si(CH2)3) were prepared by hydrosilylation of allyl-terminated PEO. They were incorporated into PDMS elastomers using classical tin-catalyzed RTV …
