Figure Lengend Snippet: 3 μm × 3 μm AFM topography maps of the top surface of bimodal colloidal films formed at 25 °C and three different relative humidities: 10% (fast), 50% (medium), and 90% (slow). (a) Corresponds to the films without added NiPc, (b) 0.1 wt % NiPc, (c) 0.5 wt % NiPc, and (d) 1 wt % NiPc. Scale bars represent 1 μm.

Article Snippet: Then, 200 μL of the colloidal blends were cast on the coverslips using a micropipette and left to film form at 25 °C and three different relative humidities (10%, 50%, and 90%) inside an environmental chamber (HCP105, Memmert).

Figure Lengend Snippet: Cross sections of films formed from a binary mixture of large (ϕ L = 0.7) and small particles (ϕ S = 0.3) obtained by confocal fluorescence microscopy with different NiPC concentrations: (a) 0.1 wt %, (b) 0.5 wt %, and (c) 1 wt %. Bright horizontal intensity lines at the film’s top surface observed in samples dried under low and medium humidities indicate NiPc is located at the upper part of the film.
