(a) Film thickness versus time profiles of the ∼220 nm nanocomposite thin films annealed under different solvent treatments during in situ GISAXS measurements. Solvent treatments A, B and C allowed the three nanocomposite thin films to reach fs=0.23, 0.31 and 0.40 in 10 min, respectively. The GISAXS patterns and the corresponding AFM phase images during solvent treatments A, B and C at the points indicated in a are shown in b,c and d, respectively. (e) The plot of the grain size as a function of fs, showing that the ordered nanostructure is optimized at fs=0.31. The dotted line is intended as a visual guide to further elucidate the trend in the grain size change. Scale bar, 100 nm.
