From: Production of silk sericin/silk fibroin blend nanofibers
FTIR spectra of SS, SS/SF blend nanofibers, heated SS/SF (50/50) blend nanofibers, and SF. Sample: a, powder form of silk sericin; b, c, d, e, f, SS/SF blend nanofibers with different compositions (100/0, 75/25, 50/50, 25/75, 0/100); g SS/SF blend nanofiber (50/50), heat-treated at 160°C for 30 min; h SF film.
