Measurements of the amount of weight change of PEG–b–PLA, chlorhexidine (CHX), and CHX-encapsulated. Thermogravimetric analysis (TGA) curves showing mass loss as a function of temperature. Note that thermal transitions for the CHX-encapsulated product most resemble the behavior and transitions measured for the PEG–b–PLA polymer due to the proportion of PEG–b–PLA being much higher than CHX.
