Figure 9From: Preparation of periodic surface structures on doped poly(methyl metacrylate) films by irradiation with KrF excimer laserAFM images of the PMMA-FR films modified by laser (by 50 pulses and 12 mJ cm−2). Thicknesses of films: (A) 0.17 μm, (B) 0.2 μm, (C) 0.67 μm, (D) 2.1 μm.Back to article page
