Effectiveness of the prepared photocatalyst for the PS degradation was estimated through FESEM, FTIR, total organic carbon (TOC) analyzer, and gas chromatography-mass spectroscopy (GC–MS).

Fourier transform infrared (FTIR) analysis shows the main distinctive absorption peaks of PS and PVK, whose intensities changed randomly after filling. Moreover, the highest TiO2 NPs content...

FTIR confirmed the presence of polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polycarbonate (PC), polyethylene (PE) and macro rubber (Ma-R ...

Nov 1, 2021 · This work describes a methodology for the reliable identification of the most abundant polymer types in aquatic sediments (polyethylene, PE, polypropylene, PP, polyethylene terephthalate, PET, and polystyrene, PS) by micro-ATR-FTIR.

Aug 1, 2024 · Through FTIR (Fourier Transform Infrared Spectroscopy) analysis, detailed information about the spectra corresponding to each plastic is sought, with their characteristic bands contributing to identify these polymers in samples containing mixtures of …

Mar 13, 2016 · Infrared Spectroscopy (FTIR) measurements of four polymers assigned to unknown spectra, examine how different bonds and functional groups give rise to different FTIR signatures and estimate % crystallinity in LDPE and HDPE as semi-crystalline polymers.

The aim of this paper is to study the morphology and the FTIR spectra of PS spheres self-assembled on various substrates. Experimental. Monodisperse polystyrene (PS) microspheres with diameters between 50 and 500 nm were provided in the form of an aqueous suspension (5.0%w/v) by Bands Inc., and Polyscience Inc.

Apr 17, 2018 · The results of the present FT-IR study suggest that the mechanisms underlying the radiation-induced damage in PS are supported by the dynamic nature of the bonds. Thus, PS is a unique electron-rich polymer which can withstand high doses of gamma radiation and which could be used for diverse plastic ware.

Nov 28, 2014 · A new idea to understand the macromolecular motion occurring along the thermal relaxations of polystyrene (PS) and PS-barium titanate composites is proposed. Detailed analysis of PS infrared bands provides a better knowledge of the factors affecting polymer dynamics.

In this study, zinc oxide nanoparticles (ZnO NPs) were successfully incorporated into polystyrene (PS) using a combination of solution casting and hot-pressing, yielding a range of PS/ZnO...
