We investigate the structural properties of Janus ligand-tethered
nanoparticles at liquid–liquid interfaces using coarse-grained
molecular dynamics simulations. The effect of interactions between
different chains and liquids is discussed. We consider the Janus particles
with symmetrical interactions with the liquids which correspond to
supplementary wettability and particles with uncorrelated interactions.
Simulation results indicate that the Janus hairy particles trapped
in the interface region have different configurations characterized
by the vertical displacement distance, the orientation of the Janus
line relative to the interface, and the particle shape. The Janus
hairy particles present abundant morphologies, including dumbbell-like
and typical core–shell, at the interface. The shape of adsorbed
particles is analyzed in detail. The simulation data are compared
with those predicted by a simple phenomenological approach. This work
can promote the applications of Janus hairy particles in nanotechnology.
