Tailoring the Density of Surface-Tethered Bottlebrushes

Abstract

Surface-tethered bottlebrushes have been prepared by ATRP grafting of the macroinitiator brush backbone onto plasmachemical-deposited poly(vinylbenzyl chloride) initiator nanofilms followed by ATRP growth of the side chains (bristles). The surface density of bottlebrushes can be precisely tailored by varying the plasmachemical deposition parameters employed for producing the poly(vinylbenzyl chloride) initiator nanolayers. Lateral force scanning probe microscopy has shown that poly(glycidyl methacrylate)-graft-poly(sodium styrene sulfonate) bottlebrush-decorated surfaces give rise to an enhancement in lubrication.

Hierarchical comb brush architectures via sequential light-mediated controlled radical polymerizations

“…Early experimental studies of comb polymer brushes employed photoiniferter chemistries; however, these systems suffer from a lack of control over molecular weight and chain density . Subsequent studies employed CRP techniques such as ATRP and RAFT, which do not allow the effect of chain density and the two‐dimensional patterning of the grafted chains to be investigate. Perhaps the most relevant study was the synthesis of surface‐initiated hyperbranched polymers by Huck and coworkers.…”

One‐Pot Synthesis of Molecular Bottle‐Brush Functionalized Single‐Walled Carbon Nanotubes with Superior Dispersibility in Water

“…The steric repulsions between the side‐chains result in an extended conformation of the main‐chain and give rise to interesting physical properties, such as shape‐persistency and hindered entanglement . Molecular bottle‐brush modified nanoparticles and surfaces have gained increasing attention for their potential applications in the area of biomaterials or microelectronic devices . Their preparation method usually involves multiple synthetic steps, including surface modification with functional groups (e.g., groups for initiation), surface‐initiated polymerization, and postmodification of polymer main‐chains with long side‐chains …”

[ 23,25 ] In this contribution, we demonstrate the fi rst example of preparation of molecular bottle-brush functionalized single-walled carbon nanotubes (SWCNTs) via a one-pot synthetic methodology. The molecular bottle-brush [i.e., poly( γ -propyl-L -glutamate)-graft-(oligo-ethylene-glycol), PPLG-g -OEG] functionalized SWCNTs showed signifi cant enhancement of dispersibility in water than that of oligoethylene-glycol (OEG) functionalized SWCNTs depending on the main-chain (i.e., polypeptide) and side-chain (i.e., OEG) lengths.…”
