Fig. 5

(A) SEM images of scaffolds obtained from PS636-b-PtBA250 solutions in 1:3 (wt %) DOX/DMF after 5 min of evaporation. (B) SAXS and (C) SEM of the scaffold after hydrolysis with TFA for 24 hours. (D) Scaffolds filled with CaCO3 generated by the reaction between CaCl2 and (NH4)2CO3. (E) Remaining inorganic structure after polymer dissolution.
