Abstract
A patterned surface structure formed from a ferrofluidic polymer resin having a plurality of magnetic nanoparticles. The polymer resin is patterned with a magnetic field that is applied to the ferrofluidic polymer resin during curing. The ferrofluidic polymer resin may be cast over a non-magnetic planar substrate. A magnetic field is applied to the ferrofluidic polymer resin to induce a pattern in a surface of the ferrofluidic polymer resin. The patterned ferrofluidic polymer resin is then cured to form the permanently patterned surface.
