An easy and economically viable route for the decoration of carbon nanotubes by magnetite nanoparticles, and their orientation in a magnetic field

Abstract

A simple, cheap and tunable approach for the decoration of carbon nanotubes by magnetite nanoparticles and their orientation in a magnetic field is reported.

Beneficial effect of carbon nanotubes on the performances of Nafion membranes in fuel cell applications

“…MWCNT-COOH) (Fig. 1) according to a previously reported technique [29]. A commercially available radical polymerization initiator, 4,4'-azo-bis-(4-cyanovaleric acid) (V501), was used, which, upon thermolysis, releases carboxylate containing alkyl radicals.…”

Magnetic solid-phase extraction using carbon nanotubes as sorbents: A review

“…In this case, pristine multi-walled carbon nanotubes (MWCNTs) were dispersed in an Fe(NO) 3 . Stoffelbach and co-workers [50] used a cyanovaleric acid derivative to modify the surface of MWCNTs through a traditional radical addition to release carboxylate groups, which served as grafting anchors for magnetite nanoparticles.…”

Electromagnetic and microwave absorbing properties of magnetite nanoparticles decorated carbon nanotubes/polyaniline multiphase heterostructures

“…Therefore, the synthesis of magnetite nanoparticles attracts a lot of interest. The synthesis of multifunctional PANI by combination of PANI with magnetite nanoparticles has been emerging to be an area of advanced research due to their exceptional and outstanding application in magnetic resonance imaging, magnetic data storage, magnetically guided drug delivery, electromagnetic interference shielding, and electrochemical bio-sensing [21][22][23][24][25]. However, due to lack of control in synthetic conditions, both morphology and size dispersion of the nanoparticles inside the polymer matrix have been challenging [26].…”
