Tuning Wettability by Controlled Roughness and Surface Modification Using Core-Shell Particles

We present a strategy to fabricate patterned surfaces with specifically designed surface roughness using self-assembly of core-shell spherical particles. on silicon wafer substrates. The shell of the particles is made from hydrophobic polymer brushes covalently grafted to the particles. The wetting behavior of the layer can be tuned by the change of the particle size ranging from 10 nm to 10 micrometers. The highest hydrophobic behavior and the lowest hysteresis (150 deg for advancing and 85 deg for receding contact angle) was documented for 5 micrometer particles.
