Figure 4:

Mean (marker) and standard deviation (error bars) of $\langle D\rangle$ measured on three separate self-assembled samples (independent experiments) for each PEG_xPCL_y copolymer, plotted against f_PCL. In most cases, error bars are smaller than symbols. The solid and open symbols represent the $\langle D\rangle$ of the PEG and PCL blocks, respectively, for the PEG₂PCL_y (blue), PEG₅PCL_y (red) and PEG₁₀PCL_y (green) copolymer series. Dashed lines are included as a guide to the eye and join the PEG $\langle D\rangle$ for each series.
