Preparation of polypropylene/carbon nanotube composite powder with a solid‐state mechanochemical pulverization process

Abstract: A solid-state mechanochemical pulverization process, that is, pan milling, was used to prepare a polypropylene (PP)/carbon nanotube (CNT) composite powder. The composite powder was then melt-mixed with a twin-roll masticator to obtain a PP/CNT composite. The morphology of the PP/CNT powder and the PP/CNT composite was investigated. The crystallization and mechanical properties of the latter were also studied. After 20 milling cycles (ca. 60 min), the average diameter of PP/3 wt % CNT composite powder particles… Show more

“…Among the most versatile polymer matrices, polyolefins such as PP is the most widely used thermoplastics in food packaging, automobile and other industrial sectors because of its well-balanced physical and mechanical properties and easy processability at a relatively low cost that makes them a excellent material [15]. Therefore, PP has been a popular matrix used to reinforce both single-wall [16][17][18] and multiwall [19][20][21] nanotubes. The reported results for these nanocomposites have been mixed, especially for mechanical properties, where Bhattacharyya et al [16] reported no significant improvement in mechanical properties, and others have shown moderate improvements in tensile strength, but decreased toughness [18].…”

“…If the ratio is greater than 1.5, then the a axis is parallel to the surface. [22][23][24][25] The results derived from DSC data and I(110)/I(040) values of the matrices are given on following Table 2. Endothermic melting point peaks in heating curves and crystallization peaks in cooling curves were clearly observed in Figure 5 Melting points of the matrices are also close and changes between 160 to 162 o C. There is not much change in melting and crystallization temperatures by DLP addition and they are similar to the results gathered in our previous study.…”
