Commercial polyethylene terephthalate (PET) film has been used as flexible substrate, and chalcogenide materials such as CdS, ZnS have been coated separately on PET film using vacuum thermal evaporation method. The structural characterisation of CdS-PET and ZnS-PET films has been performed by X-ray diffraction (XRD) pattern and Fourier transforms infrared (FTIR) spectroscopy. The surface morphology of CdS-PET and ZnS-PET films has also been investigated using scanning electron microscope (SEM). Temperature dependent mechanical study of chalcogenide-PET films has been carried out using Dynamic Mechanical Analyser (DMA). The stress-strain curves of chalcogenide coated PET films at room and elevated temperatures explain the mechanical response of these films under the different temperature.
