| Summary: | Problem statement: Current researches have shown that the thermoplastic-clay
nanocomposites have failed to live up to the earlier predictions albeit they have found some niche area
of applications. This research work therefore aimed at studying the effect of carbon nanotube as
secondary filler on the mechanical properties of polypropylene-clay nanocomposite. Approach: Hybrid
polypropylene-clay nanocomposite was prepared in the presence of Multiwall Carbon Nanotubes
(MWCNTs) as secondary additives using melt intercalation process. The effect of Multiwall Carbon
Nanotubes (MWCNTs) on the polypropylene/clay matrix was investigated in terms of dispersion using
XRD, tensile test (ASTM D 638) and notched Izod impact test (ASTM D256). These were compared
with the conventional polypropylene-clay nanocomposite. Results: The resulting composite shows
about 42% increase in the modulus, 26.20% in the tensile strength and 13.30 Kj m-2 impact strength
when compared with binary combination of PP/Clay nanocomposite. XRD patterns of PP/Clay and
PP/Clay/MWCNT nanocomposites show different diffraction peaks which are indications of
intercalation mixed with macromixing. Conclusion: This study showed that MWCNT can successfully
address the common shortcomings peculiar to PP/Clay nanocomposite. |
