Abstract This manuscript studies the formation of nanopatterns onto PET films under different experimental conditions. Homogeneous patterns with randomly distributed bumps or nanofibrils were observed depending on the plasma parameters. The influence of the power, oxygen pressure and electrode charge in the etching rate and final nanotopography is studied and discussed. The superhydrophobic properties of the nanostructured films are analysed.
