Impact of Polylactide Fluorinated End-Group Lengths and Their Dynamics on Perfluorohexane Microcapsule Morphology

We have synthesized polylactide (PLA) polymers containing five distinct lengths of fluorinated end-groups (from C3F7 to C13F27). The influence of fluorinated end-group lengths and their dynamics in chlorinated solvents (chloroform and dichloromethane) was investigated as a function of the presence of perfluorohexane (PFH) and related to the morphology of capsules of PFH obtained using these fluorinated polylactides. 19F spin–spin relaxation time...
