Comprehensive review on carbon nanotubes embedded in different metal and polymer matrix: fabrications and applications

Abstract

Carbonaceous material, especially carbon nanotubes (CNTs), have incredible exceptional properties, such as high thermal and mechanical stabilities, and good catalytic and adsorption capabilities. In recent years, hybrid nanocomposites have attained considerable attention due to the combination of unique organic and inorganic elements in a single material. Hence, these nanocomposites have been employed for various applications such as drug delivery, sensors, corrosion protection materials, flame retardant additives, and pollutant adsorbent. These nanocomposites can be fabricated through various approaches that include powder metallurgy, solution processing, reaction processing, melt processing, electrochemical, and many more. This present review mainly summarizes the various techniques for the fabrication, separation, and purification of CNTs and their nanocomposites, especially CNTs-based polymer and CNTs-based metals/ metal oxides nanocomposites. Besides, effects of CNTs embedded with polymers (such as polypyrrole (PPy), poly-aniline (PANI) and poly-thiophene (PTh), etc.) and metals/ metal oxides (such as manganese oxide (MnO2), copper (Cu), gold (Au), platinum (Pt), etc.) and how they can be employed toward innovative devices with fascinating properties for a broad range of applications. Moreover, industrial applications of CNTs-based polymer/ metal/ metal oxides nanocomposites have been discussed.

Mechanical properties of carbon nanotube reinforced polyurethane matrix using computational method: a molecular dynamics study

“…Finally, we concluded various CNTbased nanostructures inserting to pristine polymeric samples cause mechanical improvement of them. Previously, similar reports have been published in experimental studies [31][32][33][34]. In these studies, researchers indicated the addition of CNT when properly mixed and aligned will increase the mechanical properties of pristine polymer-based matrixes.…”

Review—Advances in PVC-Based Blend Nanocomposites

“…The enhancement of CNT distribution in polymer matrix has been achieved using various methods, including melt processing, in situ polymerization, coagulation precipitation, and ultrasonic dispersion. [68][69][70] Another way to improve PVC and CNT compatibility is to acid functionalize CNT. Mkhabela et al developed PVC/phosphorylated multi-walled carbon nanotube (p-MWCNT) and PVC/ virgin-MWCNT composites using a melt processing approach.…”

A comprehensive review on micropollutants removal using carbon nanotubes-based adsorbents and membranes

“…Various studies have been performed to discover effective fabrication routes to attain the finest, highly stable, and shape-controlled carbon nanotube-based nanocomposites, for instance, filling, hydrothermal, arc-discharge, chemical vapor deposition, and pyrolysis methods. In our previous work [131], a comprehensive discussion of different routes through which carbon nanotube-based nanocomposites can be developed along with their merits and demerits has been presented.
