Secondary or 3- relaxations

The protein/glycerol/water/Cloisite Na (treated) sample also showed a single Tg at 118.0 °C, 5.5 °C higher than observed in the untreated nanocomposite, due to the further restriction in molecular motion of the protein by the predominantly exfoliated dispersion of the nano-clay. The secondary (or (3) relaxation in the neat protein/glycerol/water/Cloisite Na (untreated) sample was situated at...
