Fig. 2 — (A) Chemical structures of CBS and VA. (B) TGA thermograms of CBS and VA. (C) Loading efficiencies of CBS and VA in the filaments after HME. PVA (high) and PVA (low) represent PVA/PLA feed weight ratios of 6:3 and 5:4, respectively, for CBS and ratios of 2:3 and 1:3, respectively, for VA. (D and E) Cumulative release of the CBS-loaded (D) and the VA-loaded (E) filaments in vitro. (F) Weight loss of the CBS-loaded and VA-loaded filaments after the in vitro dissolution study. Data are means ± SD (n = 3). *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001.
