Coating two surfaces with polymer brushes has been shown on many occasions to reduce friction by orders of magnitude. These ultra-low frictions are believed to stem from be the...

We will use off-specular reflectivity to probe the characteristic lateral length-scales in responsive polyelectrolyte brushes grown by surface-initiated ATRP from solid-liquid...

We will use time-resolved specular neutron reflectivity measurements to follow the in-situ growth of polymer brushes by surface-initiated ATRP. This will enable us to determine...

Electric field induced changes in the swelling of a strong polyelectrolyte brush will be investigated using neutron reflectivity. A poly(styrene sulphonate), PSS, brush will be...

We wish to develop a rational understanding of the mechanisms underlying the way water soluble polymer brushes - in particular those of polyethylene oxide/polyethylene glycol -...

We have recently studied the surface segregations of amphiphilic block copolymers blended in a matrix of cross-linked poly(dimethyl siloxane). In this system, while the...

We will use SANS to characterize dispersions of gold nanoparticles functionalized with poly(dimethyl aminoethyl methacrylate) brushes grafted from 25 nm gold nanoparticle...

We wish to understand the mechanism to which polymer brushes such as PEO resist the adsorption of protein and thus offer biocompatibility for various surface applications....

The voltage-induced actuation of a weak polyelectrolyte brush is an example of an ultrathin, remotely controlled responsive surface coating. We propose a continuation of...
