Abstract
This thesis describes the characterization of polymer tailored surfaces by means of quartz crystal microbalance with dissipation monitoring and contact angle measurement. There are three projects described in this thesis: a) investigation of adsorption of different homopolymers to silica surfaces; b) investigation of adsorption of different diblock copolymers to silica surfaces; c) investigation of sequential adsorption of diblock copolymers to silica surfaces and demonstration of the responsiveness of mixed-polymer layers. In the adsorption studies, quartz crystal microbalance with dissipation played an important role in characterization of tailored surfaces. Two methods, Sauerbrey equation and Voigt model, were used for analysis of tailored surfaces. In the surface responsiveness studies, contact angle measurement played a key role in characterization of the conformational changes of different surface.
