PMPC₂₅-PDPA₇₀ Self-Assembly Tuned by Temperature Change

(A–F) Particle size distribution measured by dynamic light scattering (DLS) of PMPC₂₅-PDPA₇₀ polymersome dispersion at pH = 7 and at T = 5^°C and 40^°C fast and slow heating (A). Corresponding TEM images of PMPC₂₅-PDPA₇₀ polymersomes formed by fast (B) and slow (C) heating. NMR titration peaks 1 and 7–9 normalized intensity as a function of the temperature and corresponding model of PMPC₂₅-PDPA₇₀ dispersion during slow heating at pH = 2 (D) and fast (E) and slow (F) heating at pH = 7.(G–I) Schematics show the corresponding arrangements of the PMPC-PDPA copolymers under the different constionds. Images were generated using the minimized structures shown in Figure 1 packed to form either planar or curved arrangements.
