Figure 2

(a) Film of neat (I) displaying grainy nanodomain features; (b) (I)/polystyrene (80/20 wt%) film showing signs of aggregation of nanograins into nanowire-like structures; (c) formation of nanowire network in (I)/polystyrene (60/40 wt%) film; (d) optimal nanowire network formation in (I)/polystyrene (40/60 wt%) film; (e) degradation of nanowire domains in (I)/polystyrene (20/80 wt%) film; (f) well-defined nanowire network of thermally annealed (I)/polystyrene (40/60 wt%) film with the polystyrene removed.
