At 0.001 M KCl, we observed very similar morphology of the films at LT as previously reported for water. The films contained locally varying morphology: aggregated monolayers and, also observed previously, fractal-like aggregates with voids between the "branches". HT films were more uniform and consistent. At both temperatures, films were in majority monolayers with rare and small 3D aggregates (usually no more than two-layered).
