Figure 4. Structure evolution.

Cryo-TEM images of the self-assembled aggregates of PAA₄₅-b-PIL₂₃ recorded after 1 h (a), 1 day (b) and 2 days (c) of adding water to the THF solution. Cryo-TEM images of the self-assembled aggregates of PAA₄₅-b-PIL₂₃ aged at 21 °C (d), 50 °C (e) and 80 °C (f). Self-assembling conditions: 2 mg ml⁻¹ THF solution of PAA₄₅-b-PIL₂₃, water/THF volume ratio (R)=1.6. (g) SAXS pattern of PAA₄₅-b-PIL₂₃ solution measured after 20 min and 2 days after adding water.
