(a) The radius of gyration Rg at different solution temperatures plotted against the process duration. X axis (duration) was plotted with Logarithm binary. (b) The surface area A calculated through Porod’s law. (c) The Porod invariant Q at different temperatures plotted against the process duration. (d) The penetration depth of dealloyed region, measured on cross-section view of ex-situ dealloyed samples. The value of A (40 °C) suddenly doubled at 1800 s. At the end of the in-situ tests (3000 s), the sample dealloyed at 40 °C offered the largest surface area, followed by the 20 °C dealloyed samples and the 60 °C dealloyed samples. The surface area of 5 °C dealloyed sample was always the smallest among the 4 series.
