Abstract
Multiwalled carbon nanotubes (MWCNTs) has been synthesized using chemical vapor deposition (CVD)
method. Al e Layered Hydroxide (AleLH) and MWCNTs nanocomposites; (1-x) AleLH þ (x) MWCNTs,
0.0  x  1; have been synthesized using citrate nitrate assisted hydrothermal technique. The crystal
structure and the functional groups of the prepared samples were examined using X-ray diffraction
(XRD) and Infrared spectroscopy (FTIR) respectively. The layered structure seemed under the highresolution
transmission electron microscopy (HRTEM), and the morphology was observed using field
emission scanning electron microscopy (FESEM). Moreover, the synthesized nanocomposites were
further characterized using Zeta potential, size analysis and Brunauere EmmetteTeller (BET) surface area
which showed their different characteristics as the MWCNTs content is changed. Thermal gravimetric
analysis assured the thermal stability of the nanocomposites over the temperature from room up to
480 C depending on the MWCNTs content. The obtained results revealed the improvement of all mechanical
properties with the increase of MWCNTs content
