*2.6. Differential Scanning Calorimetry (DSC) Study*

Thermodynamic behaviors and non-isothermal crystallinity of the samples were studied through DSC in the presence of nitrogen gas. The samples (15 mg) were placed into the container and the applied heat was set at a rate of 10 ◦C/min. After reaching to the final temperature (200 ◦C), the samples were kept for 2 min and then again cooled at the same rate down to the room temperature.
