Hybrid Effect of Nanosilicates and MWNT on Mechanical, Thermal, and Dynamic Mechanical Properties of Polypropylene

الملخص EN

A two-step process was used to prepare PP/MAPP/C15A/MWNT ternary nanocomposites system.

The effect of the addition of MWNT on the delamination of clay layers in the polymer matrix has been studied through XRD.

The similar crystallinity level was noticed after the addition of clay and MWNT together in the PP matrix through XRD.

Higher mechanical properties of the ternary nanocomposites system were noticed than neat PP and its binary nanocomposites systems.

Differential scanning calorimeter (DSC) technique was utilized to investigate the effect of both nanofillers on crystallization temperature (TC).

And a shift in TC towards higher temperature was noticed in all the nanocomposites.

Thermogravimetric analysis revealed an improved thermal stability of the ternary nanocomposites system.

The dynamic mechanical response of PP and its binary and ternary nanocomposite systems was evaluated.

The dispersion of the nanoparticles was investigated employing transmission electron microscopy (TEM).

The combined effect of clay and MWNT on the properties of PP was investigated and summarized.
