چکیده
|
Multiwalled carbon nanotubes (mwcnts) were coated with mgo nano particles using simple precipitationmethod. the growth of mg(oh)2particles was controlled by adjusting the alkaline concentration, salt concentrationand feed rate in simple precipitation method. the nanometer-sized mg(oh)2particles were precipitated on the surfaceof functionalized mwcnts by reaction between mgso4 solution and nh4oh. the samples have been characterizedby scanning electron microscopy, energy dispersive x-ray spectrometry, x-ray diffraction and thermal gravimetricanalysis. the results showed a nominally complete mgo coating over the entire outer surface of mwcnts resulting inimprovement of their oxidation durability.
