The potential use of recycled PET bottle in nanocomposites manufacturing with modified ZnO nanoparticles capped with citric acid: preparation, thermal, and morphological characterization

Abstract

We devised a fast and facile potential practical application by incorporating the guest ZnO nanoparticles (NPs) into poly(ethylene terephthalate) (PET) as a host polymer that recycled by dissolution/reprecipitation method.

Application of CuO nanoparticles modified with vitamin B1 for the production of poly(vinyl alcohol)/CuO nanocomposite films with enhanced optical, thermal and mechanical properties

“…Thiamine, known as vitamin B 1 (VB 1 ), is a water‐soluble vitamin and plays an essential role in different foods . The reaction for modification of the NPs is similar to our previous studies . The functional groups present in thiamine structure make it a proper substance for surface modification.…”

“…[13,14] The reaction for modification of the NPs is similar to our previous studies. [15,16] The functional groups present in thiamine structure make it a proper substance for surface modification. This vitamin makes more active sites on the NPs surfaces.…”

Surface Modification of ZrO2 Nanoparticles with Biosafe Coupling Agents, Preparation of Poly(vinyl pyrrolidone) Nanocomposites: Optical, Thermal, and Morphological Studies

“…The ability of these modifiers to chelate with metal oxides makes them a good choice for surface modification. [23][24][25][26][27][28] The focus of this study is the preparation of green and environmental friendly NCs. Therefore, PVP as a biocompatible polymer matrix, biosafe CA and VC as modifier agents instead of non-safe agents as well as ZrO 2 NPs as biocompatible nanofillers were chosen for the preparation of NCs.…”

“…Compared with conventional mixing, ultrasonic is faster, safe, and time-saving method with higher yields. 27 The NCs were characterized by Fourier transform infrared spectroscopy (FT-IR), UV-Vis spectroscopy, X-ray diffraction (XRD), and thermogravimetric analysis (TGA). Field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) analysis were used to determine the morphology of the obtained modified ZrO 2 and NCs.…”

“…Citric acid (CA) and vitamin C (VC) as biosafe, biodegradable, biocompatible and environmental friendly coupling agents have been used as modifier agent to prevent aggregation of NPs in the matrix as well as improve the compatibility of metal oxides with polymer matrix. The ability of these modifiers to chelate with metal oxides makes them a good choice for surface modification …”
