Heterogeneous catalysis inside a microreactor containing acid-functionalized polymer brushes

Microreactor technology represents a new and promising approach to carry out analytical and organic chemistry. 1 This is mainly due to the numerous advantages, especially in terms of increased surfaceto-volume ratio as a result of the downsizing of the dimensions (order of microns). This allows a better and faster mixing between the components of a reaction. The small dimensions created within ...

Shear of polymer brushes

We have measured the normal, lateral and hydrodynamic forces that act between polymer-brush-bearing surfaces immersed in a good-solvent medium, both when stationary and when in motion with respect to each other. At low sliding velocities we find a very marked decrease in the frictional force between the surfaces, an effect interpreted in terms of a fluid interfacial layer resulting from the non...

Srongly Charged Polymer Brushes

– Charged polymer brushes are layers of surface-tethered chains. Experimental systems are frequently strongly charged. Here we calculate phase diagrams for such brushes in terms of salt concentration ns, grafting density and polymer backbone charge density. Electrostatic stiffening and counterion condensation effects arise which are absent from weakly charged brushes. In various phases chains a...

Responsive Polymer Brushes

The review focuses on responsive/switching behavior of polymer brushes. The structure of the polymer brushes is analyzed in terms of the constitution and conformation of polymer chains. Responsive properties are widely discussed based on phase transition mechanisms in a controlled environment when changes are induced by solvent quality, temperature, concentration of ions, and interactions with ...

Poly-Electrolyte Polymer Brushes

It is shown using the mean field theory of Miklavic Marcelja that it should be possible for osmotic pressure due to the counterions associated with the two polyelectrolyte polymer brush coated surfaces (in the absence of excess salt) to support a reasonable load (i.e., about 105Pa)with the brushes held sufficiently far apart to prevent entanglement of polymers belonging to the two brushes, thus...
