An endothermic peak at above 280◦C of SF film (Figure 3(F)) attributed to
the thermal degradation of SF film due to disintegration of
intermolecular interaction. The DSC thermograms of the
blend films (Figures 3(B)–(E)) showed mixed characteristic
peaks of the two components, and thermal decomposition
was not observed. In comparison to SF film, the blend
films showed downward shifting of the moisture evaporation
which reached maximum with the CF 1 : 2 blend film.
