Temperature-Driven Self-Assembly of PMPC-PDPA Copolymer at Different Molecular Weight

(A–C) Turbidity measurement using UV/Vis absorbance at 400 nm of PMPC₂₅-PDPA₇₂, PMPC₁₂-PDPA₃₅, and PMPC₆-PDPA₁₂ solution during heating (red curves) and cooling (blue curves) starting from 5^°C to 60^°C; a photograph of the cuvette before and after heating is shown (A). TEM images of PMPC₂₅-PDPA₇₂, PMPC₁₂-PDPA₃₅, and PMPC₆-PDPA₁₂ structures formed during heating and after cooling. Scale bar, 200 nm (B). Micro-differential scanning calorimetry of PMPC₂₅-PDPA₇₂, PMPC₁₂-PDPA₃₅, and PMPC₆-PDPA₁₂ dispersion showing the heat exchange during heating and cooling (C).
