Nanocomposite ferromagnetic

The electric properties of soft ferromagnetic nanoparticles in an insulating matrix strongly depend on the concentration of a metallic filler x and are varied between properties of the matrix and those of the filler. In binary nanocomposites a critical concentration (percolation threshold Xq) is reached when a continuous current-conducting cluster of the filler particles is formed through out the sample.

An efficient one-pot synthesis of core/shell TiO /PANI-NPs from meth-acrylic acid-functionalized TiO -NPs by self-catalyzed hydroamination and oxidative polymerization of aniline was demonstrated by Bae et al. [118]. Core/shell-structured TiO /PANI nanocomposite was also fabricated by grafting aniline on aminobenzoate monolayer that is chemically adsorbed on the TiO nanocrystal surface [119]. Ferromagnetic semiconducting PANI/TiO nanocomposites [96], PANI/TiO nanocomposite photocatalysts [97], as well as composites of self-assembled PANI nanostructures with TiO -NPs [88] or TiO nanotubes [98] were synthesized by... 

An original method to fabricate oxide nanostructured magnetic materials has been proposed in Ref. [328]. The method is based on chemical modification of ion-substituted layered double hydroxides. These structures are nanocomposites based on ferromagnetic y-Fe203 nanoparticles and diamagnetic matrix, which are stable in air and have sufficient coercive force and saturation magnetization of y-Fe203. 

The interest in functional organic-inorganic nanocomposites has grown tremendously in the last two decades thanks to the development of nanotechnologies that allow the production of nanostructured components with unique physical properties and features such as superparamagnetism, ferromagnetism, size-dependent band-gap, and electron and photon transport.
