Molecular brushes were synthesized via the combination of free radical/ as well as anionic polymerization of 2-isopropenyl-2-oxazoline (IPOx) (for the backbone) and living cationic ring-opening polymerization (LCROP) of 2-oxazolines (for the side chains) through the “grafting from” method. The influence of different parameters such as molecular structure, molar mass, concentration, and side chain length upon the final polymer properties such as solubility, aggregation, thermo-responsiveness of molecular brushes was investigated. Such molecular brushes were introduced onto various substrates by self-initiated photografting and photopolymerization (SIPGP) of IPOx and successive LCROP of 2-oxazolines to form bottle-brush brushes (BBBs). The impact of side chain composition/ length and end functionalities of the BBBs on the layer morphology, wetting behavior, and protein adsorption/ cell adhesion characteristics was examined as well.
