(A) SEM images and (B) pore size analysis of RT-SF scaffolds formed from O/W emulsions after 6 h at room temperature with BuOH/SF of 1/4, 1/2, and 1/1 (macropores are marked by white arrows, and the nanofibrous SF matrix is marked by black arrows). (C) Fourier transform infrared (FT-IR) spectra of SF in the as-made O/W emulsion with BuOH/SF of 1/2 and in the scaffolds formed from these emulsions after 6 h at room temperature.
