“…Compared with non-covalently functionalized CNTs, covalently functionalized ones can interact directly with the matrix system as the polymer bound to the CNT can transfer stress directly from the matrix to the CNT structure. [9,14,17,[22][23][24][25][26][27][28] However, the characterization of functionalized CNT is still difficult because of their high absorption of electromagnetic radiation across a broad spectrum [7,8]. This leads to a very low resolution for methods based on radiation like UV/Vis and IR spectroscopy.…”

“…The very high aspect ratio makes it likely that the addition of a small amount of CNTs strongly improves the electrical [1], thermal [2] and mechanical [3] properties of the polymer matrix. Thus, CNT/polymer composites combine the good processability of the polymers with the excellent mechanical and other functional properties of the CNTs.…”

Abstract. Multi-wall carbon nanotubes (MWNTs) filled polypropylene (PP) nanocomposites were prepared through diluting a PP/MWNT masterbatch in a PP matrix by melt compounding with a twin screw extruder. Polypropylene grafted maleic anhydride (PP-g-MA) was used to promote the carbon nanotubes dispersion. The effect of PP-g-MA addition on the rheological, mechanical and morphological properties of the nanocomposites was assessed for different MWNTs loadings. Scanning electron microscopy (SEM) has shown that nanotubes are distributed reasonably uniformly. A better dispersion and good adhesion between the nanotubes and the PP matrix is caused by wrapping of PP-g-MA on MWNTs. When PP-g-MA is added, dynamic moduli and viscosity further increases compared to PP/MWNT nanocomposites. The rheological percolation threshold drops significantly. Tensile and flexural moduli and Charpy impact resistance of the nanocomposites also increases by the addition of PP-g-MA. The present study confirms that PP-g-MA is efficient to promote the dispersion of MWNTs in PP matrix and serves as an adhesive to increase their interfacial strength, hence greatly improving the rheological percolation threshold and mechanical properties of PP/MWNT nanocomposites.
