“…This alternative method for insoluble polymers is frequently used to create thermoplastic polymer blends and composites. It also offers a relatively simple CNT/polymer composite fabrication method that is highly compatible with existing polymer processing methods such as injection, extrusion, and compression molding, opening up new opportunities for large-scale production [74]. The thermoplastic polymer pellets used in this process can melt (see Fig.…”

The demand for increased performance in structural materialshasdrawn attention to the use of fiber materials as a means of reinforcement to provide structural integrity. Carbon nanotube (CNT) reinforced polymer nanocomposites have become the go-to materials due to their superior properties. CNTs possess a strength 10-100 times higher than steel yetare lighter in weight. Additionally, CNTs have a remarkable thermal stability of up to 2800°C in a vacuum, and an electrical conductivity of 103 S/cm. It also has an electric-current-carrying capacity 1000 times higher than other materials and a thermal conductivity of around 1900 W m-1K-1, which is almost double that of diamond. This article explores the potential of Carbon Nanotubes (CNTs) to reinforce structural composite materials, improve sensing, and enhance responsiveness. It also examines its structure and classification as single and multi-walled, its synthesis,including laser ablation methods, arc discharge methods, chemical vapor deposition methods, and spray pyrolysis. Additionally, it discusses the applications,structural benefits,and challenges ofcomposite materials.

“…Moreover, it is extracted from snails’ shells, pearls, and eggshells as well because it is their main ingredient of them. Limestone has the advantages of low viscosity and high thermal conductivity and produces a high homogenous mixture with good dispersion in the polymer matrix [ 42 , 43 , 44 , 45 , 46 ].…”

“…In MD simulations, the trajectories of system constituents are estimated using Newton's equations of motion. In this respect, the potential energies and the particles forces are calculated based on the molecular mechanics force fields or interatomic potentials [14]. It should be mentioned that all of the MD simulations were carried out through the COMPASS force field, in which, the total potential is composed of three main components, including bond energy terms, cross energy terms and non-bond energy terms, as expressed by Equations ( 1)-(4) [15,16]:…”

Biopolymers are widely used in surface modification of magnetic nanoparticles for biomedical applications. To improve the functionality of nanoparticles, it is of great significance to study the interaction mechanisms between these nanoparticles and biopolymers at the atomic level. Hence, in this study, the adsorption process of three different biopolymers (Gum Tragacanth, pectin and carrageenan) on Fe3O4 nanosurface was investigated through molecular dynamics (MD) simulations. In this regard, the adsorption process was first simulated under NVT (constant number of molecules, volume and temperature) condition. Then, the details of the interaction mechanisms between the biopolymers and Fe3O4 were comprehensively studied based on the interaction energies, concentration profiles and radial distribution functions. The obtained results indicated that all of the biopolymers were well adsorbed on the Fe3O4 surface, as a result of the interaction between Fe3O4 and the active atoms of the polymer chains. These interactions were mainly caused by hydrogen bonds formation and van der Waals forces. According to the obtained results, the strongest binding belongs to Fe3O4/carrageenan, followed by Fe3O4/Gum Tragacanth and Fe3O4/pectin, respectively.
