Statistical thermodynamics of block copolymer adsorption
The aim of this study was to develop a statistical thermodynamic theory for the adsorption of linear flexible block copolymers from a multicomponent solution. This has been accomplished by a more general derivation of the self-consistent field theory of Scheutjens and Fleer for adsorption of homopolymer from a binary mixture, introducing local segm...
Competitive adsorption of albumin and monoclonal immuno upsilon globulin molecules on polystyrene surfaces
The subject of this thesis is proteins at interfaces. The main purpose of the work was to acquire more insight into the mechanism of adsorption of Bovine Serum Albumin (BSA) and monoclonal Immuno gamma Globulins (IgG's). both individually and in competition. Another aim was to achieve optimum conditions for the colloidal stability of polystyrene (P...

Displacement of adsorbed polymers : a systematic study of segment - surface interactions
This thesis describes a method to determine the thermodynamic (reversible) adhesion strength of polymers on inorganic solids.This adhesion strength of polymers is an important factor in many applications. Examples are the quality and properties of glass fibre reinforced composites, coatings, and adhesives.The key idea of the method is that the ther...
Kinetics of polymer adsorption, desorption and exchange
The aim of the study in this thesis was to gain more insight in the kinetics of polymer adsorption. To this end some well-characterised polymers have been systematically investigated.In the process of polymer adsorption one may distinguish three kinetic contributions: transport to the surface, attachment, and reconformation of the adsorbing and ads...

Adsorption of charged diblock copolymers : effect on colloidal stability
In this thesis we present Scheutjens-Fleer (SF) calculations on the adsorption of diblock copolymers. More specifically, we restrict ourselves to adsorption at uncharged surfaces, while the specific type of block copolymers we consider have one uncharged adsorbing "anchor" block and one non-adsorbing charged "buoy" block. We compare these systems w...
Copolymers at the solid - liquid interface
Copolymers consisting of both adsorbing and nonadsorbing segments can show an adsorption behaviour which is very different from that of homopolymers. We have mainly investigated the adsorption of AB diblock copolymers, which have one adsorbing block (anchor) and one nonadsorbing block (buoy). The anchors adsorb from solution onto a surface and the ...
