The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 2.2 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00034 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

RÉSUMÉ

This article is an attempt to identify the topics that are most relevant to carbon nanotube/polymer (CNT/polymer) materials. Publications in which mechanical properties like stiffness and damping have been predicted are reviewed. The effects of volume fraction (Vf) and aspect ratio (l/d) on the mechanical properties of composites reinforced with single-walled CNTs (SWCNTs) have been studied using molecular dynamics (MD) simulations. Results showed that the longitudinal Young’s modulus of the composite is strongly dependent on l/d and CNT Vf. Simulation results have been compared with the rule of mixture model, periodic microstructure model, Finegan model, and Mori–Tanaka model. To the best of the knowledge of the authors, there is no other study which has compared the MD results with the abovestated models. Hence, this will be a valuable addition to the literature. When 2% CNT was added to polyethylene, the value of E11 was increased to 20.69 GPa, i.e., an increase of 20 times. E11 increased considerably until Vf = 0.06. Thereafter, the rise was minimal due to the slippery nature of CNT, which does not assist in further improvement of mechanical properties. When l/d changes from 5 to 10, E11 increases approximately 47.5%. MD results have been found to agree well with the analytical models.
