  3. 2. Modification of Surface Properties Through Polymer Adsorption. Kinetics, Interaction, Degradation and Stability

    Författare :Dries Muller; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TIRF.; protein; poly lactide ; poly ethylene oxide ; gelatin; exchange; enzyme; ellipsometry; desorption; degradation; adsorption; copolymers; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The interfacial behaviour of polymers in relation to surface modification and polymer degradation was studied. In the first part the interfacial behaviour of amphiphilic poly(ethylene oxide)–poly(D,L-lactide) (EmLn) diblock copolymers at hydrophilic and hydrophobic substrates from aquous solution was studied.
