title: Photothermally actuated interfacial hydration for fast friction switch on hydrophilic polymer brush modified PDMS sheet incorporated with Fe3O4 nanoparticles.
abstract: A near-infrared light triggered fast interfacial friction switch was achieved with polyelectrolyte brush grafted PDMS embedded with Fe3O4 nanoparticles, where the in situ heating up of the photothermal Fe3O4 nanoparticles in the polymer matrix changes the interface humidity and thereafter alters the hydration level of the interfacial polymer brushes.
