a SAXS and b WAXS profiles of PBLG30-b-PTPLGns annealed hot-pressed films, compared to two homopolymers. c Schematic representation of head-to-head bilayer lamella structure of PBLG30-b-PTPLG75. Top: the theoretical polymer length calculated based on a helical pitch of 0.54 nm. Middle: overall block copolymer structure. Bottom: the packing scheme of two blocks in their respective domains. PBLG and PTPLG are indicated by green and red colors, respectively.
