Figure 1.
Phase diagram constructed for Gx-Hy diblock copolymer nano-objects to determine the precise copolymer composition for the pure worm phase. Each point represents the copolymer morphology assigned on the basis of post-mortem TEM studies. Green squares indicate spheres, red circles indicate worms, and blue squares indicate vesicles. Shaded boundaries represent regions of uncertainty. The three stars indicate the specific copolymer compositions used in this study. All copolymer syntheses were conducted at 20% w/w solids except for those involving PGMA DPs below 47, which were conducted at 10% w/w solids. These can be included in this phase diagram because the copolymer morphologies produced using such short stabilizer blocks exhibit no concentration dependence.
