Description	This contribution presents the results of plasma modification of rigid and flexible polymethyl methacrylate (PMMA) using Diffuse Coplanar Surface Barrier Discharge (DCSBD) generated in pure hydrogen at atmospheric pressure. After the several minutes of the plasma treatment, a timedependent and plasma gap-dependent formation of nanoscale pillar-like structures was observed on rigid and flexible PMMA surface. The structuring and etching of substrates were investigated by a scanning electron microscopy. Atomic force microscopy revealed an increase of surface roughness in the order of 10.
