Figure 3

Nanoparticles formed by PEtOxm-b-POx1n copolymers of 0.5 mg mL–1 in ethanol after sonication for 30 min in the presence of ice bath. TEM images of (A) PEtOx4-b-POx15, (B) PEtOx10-b-POx16, and (C) PEtOx42-b-POx17. Insets display the length/size distribution histograms (based on measurements of ∼100 individual particles). (D) DLS measurements for the copolymers in ethanol (0.5 mg mL–1; inset: cartoon representing the size difference in the micelle-like assemblies). Typical SEM images of the xerogels obtained by drying the organogels formed with 15 wt% of (E) PEtOx10-b-POx16 and (F) PPeOx10-b-POx16 in (R)-carvone in an oven (60 °C for 3 days). (G) Photographs of macroscopic gels formed by PPeOx10-b-POx16 in (R)-carvone (a), citronellal (b), and (R)-limonene (c), and by PEtOx10-b-POx16 in (R)-carvone (d) and citronellal (e).
