C 1 s STXM study of polystyrene–polyisoprene–polystyrene (PS–PI–PS) free-standing thin films. Sample A was heated and cooled at 3 K min−1 to 363 K, whereas sample B was heated and cooled at 1 K min−1 to 383 K, above the glass transition temperature (Tg) of PS. The left-hand maps are of the PS component derived from a stack-fit analysis. Three-dimensional plots of the PS and PI component maps are presented for samples A and B, along with line profiles across the structures.
