Summary

CNT based mostly nanocomposites are recognized to have superior mechanical properties, resembling elastic modulus (E), tensile energy (σ), and so forth., in comparison with different nanocomposite supplies. Historically E of the nanocomposites is measured by direct strategies just like the three-point bend check, four-point bend check, and so forth., that are damaging. Nonetheless, it’s doable to find out their E worth by an oblique technique, specifically Raman spectroscopy, which is nondestructive. On this paper, 4 completely different CNT composites have been ready, resembling CNT-SiO₂, CNT-NiO, CNT-NiMgAl, and CNT-NiOFe by pyrolyzing waste plastic with SiO₂, NiO, NiMgAl, and NiOFe catalysts, respectively. The ready CNTs are multiwall sorts with diameters and the variety of partitions are within the vary of 4.88–108 nm and 5–133, respectively. The E of the ready CNT composites have been decided utilizing Raman spectra and located to be within the vary of 4.99-28.63 GPa, that are throughout the vary of different reported CNT composites (∼1.5-95.40 GPa). The current work will assist in the research of the measurement of mechanical properties of CNT based mostly nanocomposites by nondestructive strategies.
