Such polymer brushes enable the coating of surfaces with organic thin films. Depending on the polymeric material, the properties of the polymer brush can be tailored for specific applications. This includes sensitivity to external stimuli, to which the PBes may respond (e.g. temperature, pH, …).
Furthermore, PBes can be used to immobilize small particles introducing additional properties to the so-called composite material. One of many existing examples is the attachment of inorganic nanoparticles (e.g. gold or cobalt nanoparticles) to the PBes.
The group synthesizes PBs via Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP) reaction. Frequently used analysis methods for the polymer brushes are ellipsometry, AFM, X-ray (XRR), and neutron reflectometry (NR).
