Modification of the
Polysterene Surface by BSA/Tween-80 Complex and Forecast of Biocompatibility
Abstract
Polystyrene surface was
modified by the complex of Tween-80–BSA. Complex adsorption and a film
formation have been established using piezoelectric weighing method.
State of modified surfaces
was evaluated by contact angle measurements. Stability of modifying layers has
been determined on the basis of critical values of interfacial energy after
contacting of samples with water during 12 hours. Potential possibility is
discussed for complex applications to enhance the biocompatibility of polymer
materials.
