In this study, therefore, multi-walled carbon nanotubes (MWCNTs) were prepared on account of morphology, particle size and thermal properties of CNTs from high-density polyethylene (HDPE) waste and polypropylene (PP) using pyrolysis in the presence of Fe/Mn/Al catalyst. A comparison between the produced CNTs and commercially available CNTs was conducted to analyse if any deviations exist between both products. It was discovered that The commercial CNTs properties have similarities with the MWCNTs produced from plastic wastes. These materials were found to differ in purity with 1% error. The structures and morphologies of these materials are comparable as they were found to be crystalline and they revealed lattice fringes. They differ by the planes in the structural orientation. The MWCNTs synthesized from plastic wastes showed low thermal stability as opposed to the commercial CNTs.

Point To Point

HREM studies of the carbonaceous material deposited on the cathode of a Huffman-Krätschmer arc reactor have shown a rich variety of multiple-walled nano-clusters of different shapes and forms. The preparation of the samples, as well as the variety of cluster shapes, including triangular, rhombohedral and pentagonal projections, are described elsewhere.The close registry imposed on the nanotubes, focuses attention on the cluster growth mechanism. The strict parallelism in the graphitic separation of the tube walls is maintained through changes of form and size, often leading to 180° turns, and accommodating neighboring clusters and defects. Iijima et. al. have proposed a growth scheme in terms of pentagonal and heptagonal defects and their combinations in a hexagonal graphitic matrix, the first bending the surface inward, and the second outward. We report here HREM observations that support Iijima’s suggestions, and add some new features that refine the interpretation of the growth mechanism. The structural elements of our observations are briefly summarized in the following four micrographs, taken in a Hitachi H-8100 TEM operating at an accelerating voltage of 200 kV and with a point-to-point resolution of 0.20 nm.
