Novel chemical synthesis and characterization of copper pyrovanadate nanoparticles and its influence on the flame retardancy of polymeric nanocomposites

Abstract

In this work, copper pyrovanadate (Cu3V2O7(OH)2(H2O)2) nanoparticles have been synthesized by a simple and rapid chemical precipitation method. Different copper-organic complexes were used to control the size and morphology of products. The morphology and structure of the as-synthesized products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectrum, electron dispersive X-ray spectroscopy (EDX), thermal gravimetric analysis (TGA), differential thermal analysis (DTA) and photoluminescence (PL) spectroscopy. The influence of copper pyrovanadate nanostructures on the flame retardancy of the polystyrene, poly vinyl alcohol and cellulose acetate was studied. Dispersed nanoparticles play the role of a magnetic barrier layer, which slows down product volatilization and prevents the flame and oxygen from the sample during decomposition of the polymer. Cu3V2O7(OH)2(H2O)2 is converted to Cu3V2O8 with an endothermic reaction which simultaneously releases water and decrease the temperature of the flame region.

Eco-friendly date-seed nanofillers for polyethylene terephthalate composite reinforcement

“…Nanoscale fillers can be of different shapes and sizes, which can be categorized into three types, namely twodimensional (2D) layered, one-dimensional (1D) fibrous or zero-dimensional (0D) spherical nanofillers [36]. Nanofillers exhibit ultra-large interfacial areas when bonded to polymer matrices, and are used particularly to improve polymer properties through serving as reinforcing materials and acting as active ingredients [3,4,37]. Specifically, the reinforcement of a polymeric matrix with a nanofiller would render the composite with several mechanical, electrical, thermal, and magnetic characteristics [38].…”

Exploration of structural, thermal and spectroscopic properties of self-activated sulfate Eu2(SO4)3 with isolated SO4 groups

“…To fill this gap, in the present work, the polycrystalline powder of Eu2(SO4)3 has been synthesized and the crystal structure of the sulfate has been determined for the first time. It might be well to point that much research on synthesis of materials for various applications by different methods, including the green chemistry approach, were conducted resently [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63]. However, to provide synthesis of stoichiometric Eu2(SO4)3 compound, the precipitation approach was used in the present study.…”

Mechanochemical conversion of nano potassium hydrogen terephthalate to thallium analogue nanoblocks with strong hydrogen bonding and straight chain metalophillic interactions

“…It is good to know that particle size and morphology of nanostructures depend on their synthesis method. For example, extensive research on synthesis of iron vanadate is being conducted using different techniques such as sol–gel, wet chemical, microwave, hydrothermal, solid‐state and precipitation . Among several different synthetic paths, many kinds of CPs have been prepared by sonochemical method .…”
