The effect of surface plasma modification of different lengths of time on surface topography and roughness. AFM images of Parylene C and Parylene N surfaces demonstrated slight increases in introduced surface area and roughness on plasma-treated Parylene C as the treatment time increased. Noticeable changes were not observed in plasma-treated Parylene N. The X–Y (0–1 µm) and Z-axes (0–15 nm), as well as the intensity mapping, are all set to the same scale in each AFM image.
