The impact of tetrahydrofuran (THF), a good solvent for the crystallizable core-forming block (PCL), was investigated. Fig. illustrates the overall inhibitory effect of THF addition: Increasing the volume fraction of good solvent hinders the platelet growth rate, as crystallization is slowed due to enhanced polymer solubility. Generally, we observe that the final area of platelets generated from fixed unimer and seed concentrations remains consistent, regardless of solvent compositions (0 to 3% of THF). However, notably, this does not hold true for the highest THF concentration we explored (Fig. , purple, 5%).
