Nanocomposites with size-controlled nickel nanoparticles supported on multi-walled carbon nanotubes for efficient frequency-selective microwave absorption

Smart Nanocomposites for Nanosecond Signal Control: The Nano4waves Approach

“…As an example, Figure 15a shows the TEM micrograph of a 1% PC MWCNT nanocomposite, in this figure a network of individual MWCNTs is clearly observed. A similar study was performed as detailed in [25] for PC films containing MWCNTs decorated with Ni particles, synthesized under ambient (AP) pressure or in autoclave (AC) using a solvothermal method. The procedure (AP or AC) enables control of the size of the Ni MNPs, which influences the saturation magnetization M s , and hence the FMR frequency.…”

Influence of TiO2 nanofiller geometry on the rheological and optical properties of poly(acrylic acid)‐based nanocomposite hydrogels

“…The nanoparticle characteristics, such as size, geometry, concentration, dispersion, and orientation, are important variables to consider in the synthesis of nanocomposite materials due to their relevant effect on the properties of the final material. [3][4][5] Generally, the effect of nanoparticles on the macroscopic properties of a polymer is highly dependent on the nanoparticle-polymer interfacial region, specifically the area where the nanoparticles encounter the polymer chains. The characteristics of this interfacial region depend on the type of bonding between the material phases and, ultimately, on the interference that the nanoparticles may pose on the mobility of the flexible polymer chains.…”

“…Currently, many commercially available or synthesizable nanostructures of different natures are available, such as carbon‐based materials or inorganic nanoparticles. The nanoparticle characteristics, such as size, geometry, concentration, dispersion, and orientation, are important variables to consider in the synthesis of nanocomposite materials due to their relevant effect on the properties of the final material 3–5 …”
