Enhanced Gas Sensing Properties of Graphene Transistor by Reduced Doping with Hydrophobic Polymer Brush as a Surface Modification Layer.

ACS Applied Materials and Interfaces, 2020
Surface modification layer of a silicon substrate has been used to enhance the performance of graphene field-effect transistors (FETs). In this report, ultrathin and chemically robust polymer brush was used as a surface modification to enhance the gas ...

Conformation in ultrathin polymer brush coatings resolved by infrared nanoscopy.

Analytical Chemistry, 2020
Polymer brush coatings are effective in preventing blood coagulation or bacterial attachment, but their chain conformation, while vital for this effect, was never characterized in high spatial resolution.

Thermoresponsive Polymer Brush Modulation on the Direction of Motion of Phoretically Driven Janus Micromotors.

Angewandte Chemie, 2019
We report a thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) brush functionalized Janus Au-Pt bimetallic micromotor capable of modulating the direction of motion with the change of the ambient temperature. The PNIPAM@Au-Pt micromotor moved along the

Polymer Brush Graft-Modified Starch-Based Nanoparticles as Pickering Emulsifiers.

Langmuir, 2019
We study biosourced core-shell particles with a starch-based core and thermo-responsive polymer brush shell using surface-initiated single-electron transfer living radical polymerization (SI-SET-LRP) as a Pickering stabilizer.

Co-Nonsolvency Response of a Polymer Brush: A Molecular Dynamics Study

Macromolecules, 2019
Using molecular dynamics simulations, we study the response of a polymer brush exposed to co-nonsolvent (CNS), which acts as a preferential solvent for the polymer.

Local Structure and Relaxation Dynamics in the Brush of Polymer-Grafted Silica Nanoparticles.

ACS Macro Letters, 2018
When grafted to spherical nanoparticles at high grafting densities, polymers adopt a variety of conformations. Because of strong confinement by neighboring chains, portions of the polymer near the nanoparticle core are highly stretched in the ...
