Synthesis and characterization of MWCNTs/Co1−Zn Fe2O4 magnetic nanocomposites and their use in hydrogels

Synthesis, structural, magnetic and electrical properties of Co1−xZnxFe2O4 (x=0.0, 0.2) nanoparticles

“…Cobalt ferrite is well-known hard magnetic material due to its high saturation magnetization ($80 emu/g) and high coercivity (5400 Oe) [30]. However, these values may significantly differ in the nanosized particles due to particle size and synthesis method dependence of magnetic properties of [31][32][33][34][35]. The reduced magnetization explained by Coey et al [36] with the different spin configuration that is found in large particles called Neel type.…”

Encrustation of cobalt doped copper ferrite nanoparticles on solid scaffold CNTs and their comparison with corresponding ferrite nanoparticles: a study of structural, optical, magnetic and photo catalytic properties

“…Similar synthesis techniques were employed to axially decorate mixed spinel ferrite nanoparticles on the tubular surface of carbon. Chen et al 21 synthesized the zinc doped cobalt ferrite-CNT nanocomposite with solvothermal method. However, aggregation of ferrite nanoparticles in the form of lumps of around 100 nm was observed from the Transmission Electron Microscope (TEM) images.…”

A Comprehensive Study of Pristine and Calcined f-MWCNTs Functionalized by Nitrogen-Containing Functional Groups

“…Thus, CNTs can be considered as a hexagonal array of carbon atoms wound in a hollow cylinder in two ways: single-walled nanotubes (SWCNTs) and multi-walled (MWCNTs) nanotubes [ 1 ]. These materials are characterized in particular by (i) outstanding mechanical and structural properties; (ii) good surface to area ratio; (iii) unique electrical conductivity; (iv) chemical and thermal stability, making them attractive components for nanohybrids [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Nevertheless, CNTs, usually in their pristine form, tend to aggregate by forming agglomerates combined with van der Waals interactions [ 16 ].…”

“…Understanding the impact of the functionalization type on the various properties of CNTs is one of the key factors for their potential future applications. Keeping in mind the development of nanotechnology, the electronic and magnetic properties of CNTs could be exploited, for example, in the design and synthesis of nanocomposite materials [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. In general, MWCNTs are promising candidates for building blocks to build nanocomposites.…”
