Rapid Fabrication of Periodic Patterns on Poly(styrene-co-acrylonitrile) Surfaces Using Direct Laser Interference Patterning

Figure 2

(a) FTIR spectra of SAN copolymers. (b) Relationship between the % of styrene in the feed and the % of styrene units in the copolymer. Next to each copolymer point, the value of measured glass transition temperature is depicted. Full line is a polynomial fitting of the data. Dashed line represents the relationship for equal reactivity between acrylonitrile and styrene.
