The DSC (differential scanning calorimetric) analysis was also carried out for both micellized DT suspension using a Perkin Elmer's DSC 8000 equipment. The samples of interest underwent heating from 10 ºC-90 ºC with 1 ºC/min heating rate. The amount of heat energy required to raise the temperature of the material under investigation (i.e. heat flow) was calculated with respect to temperature. Furthermore, the FTIR spectra was recorded at 25 °C and measured in the range of 500 to 4,000 cm -1 by a Bruker Alpha II FTIR-ATR spectrophotometer .
