The stimulus-responsive polymers have attracted great attentions, because of their deformation ability under certain stimuli like moisture. In this work, the nanoimprinting technique was introduced to fabricate nanostructures (diffraction gratings and hexagonal dots) on poly(vinyl alcohol) (PVA) and poly(acrylic acid) (PAA) stimulus-responsive polymer. The imprinted PVA/PAA polymeric structures show...
