Molecular bottlebrushes were prepared by ICAR (initiators for continuous activator regeneration) atom transfer radical polymerization (ATRP) and supplemental activator and reducing agent (SARA) ATRP in the presence of 50 ppm Cu-based catalyst. Poly(

Bottlebrush macromolecules can be regarded as molecular tensile machines, where tension is self-generated along the backbone due to steric repulsion between densely grafted side chains. This intrinsic tension is amplified upon adsorption of bottlebru

Polymer bottlebrushes may be viewed as hairy flexible cylinders with a long backbone and a thick corona of densely grafted polymer chains. The corona not only controls the bottlebrush diameter, but also provides an additional drag force. We report th

Phototunable supersoft elastomers were prepared by photo-cross-linking molecular bottlebrushes with poly(n-butyl acrylate) (PBA) side chains. Bottlebrushes were synthesized by atom transfer radical polymerization (ATRP) and Br-chain end functionaliti

The structure and linear viscoelastic behavior of four different model star polymer melts were investigated experimentally. The star polymers were prepared via different synthetic routes based on atom transfer radical polymerization (ATRP). Stars wit

Molecular tensile machines are bottlebrush molecules where tension along the backbone is self-generated due to steric repulsion between the densely grafted side chains. Upon adsorption onto a subst...

Molecular bottlebrushes with hydrophobic poly(n-butyl acrylate) or polystyrene and hydrophilic poly(di(ethylene glycol) ethyl ether acrylate)) side chains were successfully synthesized by grafting from a poly(2-(2-bromoisobutyryloxy)ethyl methacrylat

Spontaneous degradation of bottlebrush macromolecules on aqueous substrates was monitored by atomic force microscopy. Scission of C─C covalent bonds in the brush backbone occurred due to steric repulsion between the adsorbed side chains, which gene

The self-organization and dynamics of bottlebrush polymers consisting of poly(2-bromoisobutyryloxyethyl methacrylate) (PBiBEM) backbone and grafted n-butyl acrylate (PBA) chains are studied as a function of the side-chain length by X-ray scattering,
