Surface modification of poly (styrene-b-(ethylene-co-butylene)-b-styrene) elastomer and its plasma protein adsorption by QCM-D

- Grafting concentration of PEG was defined by the peak-area ratio of [C-O]/[C].
- Quantitatively investigated the adsorption processes of BSA and fibrinogen using QCM-D.
- The inactivated BSA on SEBS surface could induce the subsequent fibrinogen adsorption.
- SEBS-g-PEG with graft concentration of 0.207 has excellent protein resistance.
