Influence of nanotube physicochemical properties on the decoration of multiwall carbon nanotubes with magnetic particles

摘要: Two types of commercial multiwall car- bon nanotubes (MWCNTs) with different diameters and physicochemical properties were decorated iron oxide nanoparticles obtained by hydrolysis at high temperature in the presence triethylene glycol iron(III) chloride as metal precursor. A homoge- neous distribution 2-9 nm diameter particles dec- orating MWCNTs was achieved using a weight concentration 1:1 or 1:2 nanotube respect to precursor for 30 min reflux. Detailed characterization as-received allowed correlate influence initial their decoration. The results indicate that more decoration larger magnetization are density defec- tive/reactive sites surface area.
