Avatar 330 ft ir apparatus

An Avatar 330 FT-IR apparatus (Thermo-Scientific, Waltham, MA, USA) was used to analyse the Fourier-Transform Infrared Spectra of the raw materials and the prepared polymer films. The apparatus was equipped with a coupled Zn/Se horizontal attenuated total reflectance (HATR) unit. The films were put on a clean crystal of the apparatus. The range of wavelength was 600 to 4000 cm⁻¹ during the investigation. The spectra were collected from 128 scans at the spectral resolution of 4 cm⁻¹ with CO₂ and H₂O for correction.

The FTIR spectra of the raw materials and the polymer films were investigated with an Avatar 330 FT-IR apparatus (Thermo-Scientific, USA). The equipment was coupled with a Zn/Se HATR (horizontal attenuated total reflectance) plate. The films were put directly on a clean crystal of the apparatus. The applied spectral range was 600–4000 cm⁻¹ during the investigation. The spectra were collected from 128 scans to obtain smooth spectra, at the spectral resolution of 4 cm⁻¹ with CO₂ and H₂O correction. The aim of the FTIR measurement was to investigate and determine the chemical interactions between the components of the films. FTIR spectroscopy demonstrated the different interactions that take place in the polymer film system, as can be seen in the results. The explanation of physical phenomena usually derives from chemical processes, therefore it is required to know the chemical background. We tried to find a connection between the chemical interactions and the other properties of the films.
