Water content of MeOH-annealed silk fibroin films analyzed with TGA. (a) TGA mass loss profiles with respect to temperature for 30%, 40%, 50%, and 60% MeOH-annealed silk films hydrated in dH2O. Initial plateau between 50°C-275°C corresponds to the mass remaining after water loss due to evaporation. Water content of films increases with decreasing MeOH concentrations. (b) TGA 1st derivative profiles for MeOH-annealed silk films. Primary peaks correspond to rate of evaporative mass loss while secondary peaks indicate material degradation.
