Robust superhydrophobic poly(L-lactic acid) (PLLA) substrates are prepared using a new phase-separation-based method. The wettability of the surfaces can be controlled in the range from superhydrophobic to superhydrophilic using argon-plasma treatment. The figure shows water droplets with different contact angles on differently modified PLLA surfaces superimposed on a SEM image of a rough surface.
