Ft ir 6000 fourier transform spectrometer

The experimental conditions used for the physicochemical characterization of all LSPE/xSBA-15 and LDPE/xTEO@SBA-15 films are described in detail in previous recent publications [21 (link),23 (link),24 (link)]. Briefly, a Bruker XRD D8 Advance diffractometer, Bruker GmbH, Mannheim, Germany was employed to carry out XRD analysis to all films i.e., LDPE/xSBA-15, LDPE/xTEO@SBA-15, and the pure LDPE films, to define the crystal structures of the resulted materials. The interactions between the incorporated SBA-15 and TEO@SBA-15 nanostructures with the LDPE polymeric matrix were studied using an FT/IR-6000 JASCO Fourier-transform spectrometer, JASCO company, Easton, MD, USA.

The chemical structure and the possible interactions of PLLA chains with NaMt, OrgMt, TO@NaMt, and TO@OrgMt nanostructures of all PLLA/NaMt, PLLA/TO@NaMt, PLLA/OrgMt, and PLLA/TO@OrgMt films were studied by IR spectra measurements. The obtained infrared (FTIR) plots were the average of 32 scans at 2 cm⁻¹ resolution and were measured using an FT/IR-6000 JASCO Fourier transform spectrometer (JASCO, Interlab, S.A., Athens, Greece) in the wavenumber range of 4000–400 cm⁻¹.

The chemical structure of both ZnO@Mt and ZnO@HNT hybrids was confirmed by IR spectra measurements. The measurements were carried out with an FT/IR-6000 JASCO Fourier transform spectrometer (JASCO, Interlab, S.A., Athens, Greece). For all measurements, the frequency range was 4000 to 400 cm⁻¹. The obtained infrared (FTIR) spectra of each measurement were the average of 32 scans at 2 cm⁻¹ resolution.

The chemical structures of the modified CS_RO, CS_MO, and raw CS powder samples as well as of the obtained LDPE/CS, LDPE/CS_RO, and LDPE/CS_MO nanostructured films were confirmed by IR spectra measurements. Infrared (FTIR) spectra, which were the average of 32 scans at 2 cm⁻¹ resolution, were measured with an FT/IR-6000 JASCO Fourier transform spectrometer (JASCO, Interlab, S.A., Athens, Greece) in the frequency range 4000–400 cm⁻¹.

The obtained TO@HNT hybrid nanostructure was characterized with XRD analysis, FTIR spectroscopy, and DSC analysis. For XRD analysis a Brücker D8 advance instrument was employed (Brüker, Analytical Instruments, S.A., Athens, Greece) and the measurements were carried out in the range 2θ = 2–30°. For the FTIR spectroscopy measurements, an FT/IR-6000 JASCO Fourier transform spectrometer (JASCO, Interlab, S.A., Athens, Greece) was employed. The FTIR spectra were recorded in the range of 4000–400 cm⁻¹ and the obtained spectra was was the average of 32 scans at 2 cm⁻¹ resolution. For the DSC experiments, a DSC214 Polyma Differential Scanning Calorimeter (NETZSCH manufacturer, Selb, Germany) was employed. Samples with an average weight in the range of 1.2–3.3 mg were tested under a nitrogen atmosphere with a heating rate of 10 K/min from 50 to 300 °C.

For the FTIR spectroscopy measurements, an FT/IR-6000 JASCO Fourier transform spectrometer (JASCO, Interlab, S.A., Athens, Greece) was employed. Prior to measurements, CS/PVOH, CS/PVOH/xNZ, and CS/PVOH/xTO@NZ films were cut in very small pieces and incorporated to the KBr used for the measurements. The measurements were carried out in the range of 4000–400 cm⁻¹, with a 2 cm⁻¹ resolution, and 64 scans for the final mean value of each point. An initial background was measured under the same conditions using pure KBr. Y-axis of all FT-IR measurements was the % transmittance.

An FT/IR-6000 JASCO Fourier transform spectrometer (JASCO, Interlab, S.A., Athens, Greece) was used to investigate the relaxations of HNT and TO@HNT materials with the ALG/G matrix. FTIR spectroscopy measurements were carried out via setting up experimental parameters and conditions as recently described [30 (link)].
