Semi-flexible polymers near interfaces : equilibrium aspects and adsorption kinetics
The first chapter is about semi-flexible polymers at a liquid-liquid interface: self-consistent-field calculations. The adsorption of semi-flexible polymers at a liquid-liquid interface largely differs from that at a solid surface. The width of the interface is an additional length scale in the problem, making the system behaviour particularly rich...
Adsorption and desorption of cellulose derivatives
Cellulose derivatives, in particular carboxymethyl cellulose (CMC) are used in many (industrial) applications. The aim of this work is to obtain insight into the adsorption mechanism of cellulose derivatives on solid-liquid interfaces.In chapter 1 of this thesis we discuss some applications of cellulose derivatives. Application of CMC in pelleting ...
Interactions between wood and coatings with low organic solvent content
The aim of the work described in this thesis is to improve the knowledge on the fundamental interactions between low VOC-coatings and wood, in particular in relation to wood protection in exterior use. To avoid environmental damage and dangerous conditions in the workplace, low-VOC paints have gained increasing importance by the use of waterborne a...
Fundamentals of interfacial and colloid science Vol III: Liquid-fluid interfaces
This volume deals with various aspects of surface tensions and interfacial tensions. Together with the phenomenon of adsorption (enrichment of molecules at interfaces), these tensions constitute the basic characteristics of interfaces. The authors try to keep the treatment systematic and deductive. Recurrent features are that each chapter begins, a...

Controlling Surface Interactions with Grafted Polymers
Published in Interface Science
The interactions between surfaces modified with grafted polymers is studied theoretically. The aim of this work is to find polymer surface modifications that will result in localized attractive interactions between the surfaces. The practical motivation of the work is to find means to control the distance between bilayers and solid supports in supp...
Partition function, metastability, and kinetics of the escape transition for an ideal chain
The exact partition of the gaussian chain squeezed between two cylinders for a phase transition in a single macromolecule is analyzed. The polymer chain is squeezed between two pistons which results in abrupt transition from a confined coil state to an inhomogeneous conformation. The landau free energy is used in a one dimensional fokker-plank equa...
