Jun 5, 2023 · ATR-FTIR spectra of PVC-P model samples (DOP 15 wt%) exposed to accelerated UV–Vis aging in the Q-SUN chamber (a) and accelerated thermal aging at 50 °C (b).

In our paper, we will demonstrate that ATR-FTIR spectroscopy is only slightly or not at all suitable for quality control of powdered, complex mixtures. They can be

Infrared spectroscopy using the Fourier transform (ATR-FTIR) and thermogravimetric analysis (TGA-DTA) have been performed. The results obtained show that the loss factor and dielectric constant...

Fenton’s reagent was used to isolate microplastics from organic-rich wastewater. The catalytic reaction did not affect microplastic chemistry or size, enabling its use as a pre-treatment method for...

Feb 1, 2021 · ATR-FTIR spectroscopic imaging is used to study Cd2+ -selective membranes. Distribution of water, polymer and plasticizer across the membranes is visualized. Surface layers 150 μm thick are enriched with water. The leakage of membrane components is slower than absorbed water release from membrane.

FTIR analysis IR transmittance spectra of pure PVC, PVDF and ZnO-doped poly- mer nanocomposite films (Figs 3 (i) and 3 (ii)) were recorded at room temperature in the region 500-4000 cm −1 . The...

We report a systematic FTIR study of the perturbation of water “sorbed” into the polymers PET and PVC as a function of crystallinity (PET) or plasticizer content (PVC).

Jun 29, 2021 · FTIR-based quantification of degradation in PVC pipes gives the chemical changes that occur in the polymer due to natural environmental stressors. The level of degradation can be estimated by the intensity of specific peaks or absorption bands found on the FTIR spectrum.

With the increasing number of actively deteriorating priceless modern and contemporary artworks made of PVC-P, there is a growing need for studies dealing with the analysis of changing characteristics of PVC-P during its aging under indoor conditions.

Since soft PVC containing a large amount of plasticizer displays an infrared spectrum that is greatly affected by the plasticizer, a variety of infrared spectral shapes are seen with soft PVC. Here we introduce and discuss the infrared spectra of this type of soft PVC.
