Thermal And Electrical Properties

One of the main issues in the production of polymer nanocomposites is the dispersion state of filler as multilayered graphene (MLG) and carbon nanotubes (CNTs) tend to agglomerate due to van der Waals forces. The agglomeration can be avoided by using organic solvents, selecting suitable dispersion and production methods, and functionalizing the fillers. Another proposed method is the use of hybrid fillers as synergistic effects can cause an improvement in the dispersion state of the fillers. In this review article, various aspects of each process that can help avoid filler agglomeration and improve dispersion state are discussed in detail. This review article would be helpful for both current and prospective researchers in the field of MLG- and CNT-based polymer nanocomposites to achieve maximum enhancement in mechanical, thermal, and electrical properties of produced polymer nanocomposites.

Processing Factors

In the present work, the mechanical, thermal and electrical properties of CNT/polymer nanocomposites are computed using numerical and analytical models as functions of material parameters (CNT aspect ratio, CNT waviness, presence of the interphase) and processing factors (CNT volume fraction, formation of agglomerates and the number and arrangement of CNTs in the agglomerates). The computation is performed using representative unit cells (RUCs) of CNT agglomerates. The RUCs are solved numerically using the FE method and analytically using the Mori-Tanaka method. At the same time, homogenization is applied in the RUCs. The results from the parametric study reveal that the considered parameters and factors govern the reinforcement effectiveness and, under specific combinations, might counterbalance the multifunctionality of nanocomposites.

The Impact

Since its discovery in 1991 and 2004, carbon nanotubes (CNTs) by Sumio Iijima, and graphene by Andre Geim and Konstantin Novoselov in 2004, these materials have been extensively studied around the world. Both materials have electronic, thermal, magnetic, optical, chemical, and mechanical extraordinary properties. International Technology Roadmap for Semiconductors (ITRS) has predicted that these nanomaterials are potential replacements of the conventional materials used in the manufacture of integrated circuits. Two of the technological aspects that both materials share and have reduced their extensive use are processing and dispersion required to homogenize the electrical properties of the materials based on them. Fortunately, these problems are being solved thanks to the ongoing investigation, and in a short time the materials used in today's electronics industry will be replaced by devices based on these novel materials. The impact of the applications of both materials in the electronics industry, as well as future trends in the following decades are discussed in this paper.

Carbon Nanotube Composites

In this work, the carbon nanotubes(CNTs) were reinforced with polypropylene(PP)matrix resins to improve the electrical and thermal properties of PP/ CNTs composites in different contents of 0,1, 3,and 5 wt.%. The surface, volume resistivity and crystallization type of the composites were investigated. As a result, the maximum degradation rate temperature of the composite is improved 30 °C, the surface resistivity and volume resistivity of composite are 5 ×106, 7 ×105,respectively, for the optimum composition of composite (CNTs 3 wt.%). The integrated XRD pattern of the composites shows the typical α-form PP crystals.
