A detailed study of the different structural transitions of the triblock copolymer PEO27–PPO61–PEO27 (P104) in water, in the dilute and semi-dilute regions, is addressed here as a function of temperature and P104 concentration (CP104) by mean of

The heat capacity (Cp) of confined polystyrene in particles is investigated in the case of close-packed structure using differential scanning calorimetry (DSC). This confined geometry allows the highest possible free surface area (3/R) in a dense mac

Publikováno v: Key Engineering Materials. :58-66

The effects of nanoconfinement on the dynamic and the glass transition (Tg) of polymers remains the focus of a lot of research since over a decade. Particularly, the glass transition temperature (Tg) and the dynamic of polystyrene (PS) were found to
