Rapid Fabrication of Periodic Patterns on Poly(styrene-co-acrylonitrile) Surfaces Using Direct Laser Interference Patterning
Figure 3
Line-like patterns produced on different SAN copolymers samples at different laser fluences: (a) 40 : 60, (c) 60 : 40, and (e) 80 : 20 (laser fluence: 610 mJ cm−2) and (b) 40 : 60, (d) 60 : 40, and (f) 80 : 20 (laser fluence = 972 mJ cm−2). In all cases the period was 5 μm and the SAN samples were irradiated with laser radiation of 266 nm (~10 ns pulse width).
