2.10. Thermal analysis
Differential Scanning calorimetry (DSC) of the film samples was
carried out in a Shimadzu DSC-60 calorimeter. Briefly, 50 2 mg
sample was taken in aluminium pans and hermetically sealed
before heating against empty reference pans from 30e150 C at
a heating rate of 8 C/min under N2 atmosphere. The thermal
transition patterns were studied and the melting points determined
using TA-60WS software.
