Fabrication of Polymer Magnetic Nanocomposites Containing Carbon Nanoparticles Doped with Cobalt Nanoclusters and Study Their Conductivity, Self-Healing and Adhesion Properties
The technology of fabrication of polymer
nanocomposites on basis of carbon nanoparticles doped with cobalt clusters,
synthesized by original Chemical Vapore Deposition (CVD) technology developed
by authors, was elaborated. Carbon shells provide both the protection of ferromagnetic
impurities from aggressive environment and new unique properties to the hybride
nanostructures. The self-assembling of magnetic clusters coated by carbon
shells presents just such example which could be used in the contemporary
materials, for example, in strong magnets, analytic instruments (nuclear
magnetic resonance tomographs) and nanosensors. Their good conductivity,
self-healing and adhesion properties were demonstrated by applying the combined
action of temperature, pressure, steady and alternating magnetic fields to
stimulate diffusion of magnetic nanoparticles in direction to defect sites. Due
to these properties fabricated magnetic polymer nanocomposites could have
perspective for potential.
