Polymer microgels, including those based on interpenetrating networks (IPNs), are currently vastly studied, and their practical applications are a matter of thriving research. In this work, we show the perspective for the use of polyelectrolyte IPN microgels either as scavengers or carriers of antiseptic substances. Here, we report that poly-N-isop...
The importance of organic materials for use in electronic devices such as OLEDs, OFETs and photovoltaic cells has increased significantly over the past decade. Organic materials have been attractive candidates for such electronic devices because of their compatibility with high-throughput, low-cost processing techniques and their capability to be p...

In kraamhokken met volledig roostervloer voldoet het Tendernova-rooster beter aan de eisen dan de Tenderfoot, de MIK-Soft en de rond geplastificeerde metalen driekantroosters
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 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 ...
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...

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...
The objective of this study was to collect systematic data on the adsorption behaviour of weak polyelectrolytes and polyampholytes. The measurements were performed on well-defined systems in order to be able to compare the results with the recently developed theories of Evers et al. and Böhmer et al. for the adsorption of weak polyelectrolytes. The...
