Contour lengths of worm micelles. A The distribution of contour length is shown for four worm micelle forming OCL polymers: OCL(2,5)(Δ), OCL(2, 7)(■),OCL(2, 8.5)(●),OCL(2, 9.2)(□). The distribution data is fit to a Zimm-Shulz model. All fits shown had R2 > 0.99. Arrows indicate the change in contour length distribution as the size of polycaprolactone block (MCH2) is increased. The bottom panel shows the population of worm micelles longer than 5 μm (Plong, left axis) and experimentally determined average contour length <L> (right axis) as a function of the size of the hydrophobic block (MCH2). The fits for Plong (R2 = 0.98) and <L> (R2 = 0.96) are shown to scale linearly with MCH2. B The concentration dependence of worm micelle length is shown for OCL (2, 9.2) polymer at three different concentrations (c). The data is fit to a Zimm-Shulz model. All fits shown had R2 > 0.97. Arrows indicate the change in contour length distribution as the concentration (c) of the polymer is increased. The bottom panel shows the number average contour length (Ln, left axis) and the experimentally determined average contour length (<L>, right axis) for OCL (2, 9.2) sample. The fits for Ln (R2 = 0.97) and <L> (R2 = 0.96) are shown to scale with c.
