Mechanisms of micellization and rheology of PEO–PPO–PEO triblock copolymers with various architectures

What can isothermal titration microcalorimetry experiments tell us about the self‐organization of surfactants into micelles?

“…It is worth noting that the enthalpy of micellization of a thermosensitive nonionic surfactant (pluronic F127) obtained using other methods such as Micro-DSC (Pham Trong et al, 2008) does not correspond to that obtained by using ITC . Certainly, the difference between the two DH mic values is due to the fact that the heat measured by Micro-DSC and the one measured by ITC do not reflect the same events.…”

Role of PPO–PEO–PPO triblock copolymers in phase transitions of a PEO–PPO–PEO triblock copolymer in aqueous solution

“…Two tiny endothermic peaks beyond the micellization peak appear at 26. other Pluronic copolymers, it is believed that these tiny peaks must be associated with some structural changes. Recently, Pham Trong et al [52] studied the mechanisms of F127 micellization and gelation and found that an endothermic peak appears in the micro-DSC curves, which is very close to the crossover of G′ and G". So, the author attributed this tiny peak to the sol-gel transition.…”

Green processing of thermosensitive nanocurcumin-encapsulated chitosan hydrogel towards biomedical application

“…The rheology study was conducted on a rheometer (HAAKE RheoStress 6000; Thermo Scientific, MA, USA) which followed Pham Trong et al [24]. Briefly, a 2-3 ml sample which was used in the tube inversion method was used for measurement.…”
