The design of nanometric electronic devices requires novel materials for improving their electrical performance from stages of design until their fabrication. Until now, several DC electrical conductivity models for composite materials have been proposed. However, these models must be valued to identify main design parameters that more efficiently control the electrical properties of the materials to be developed. In this paper, four different models used for modeling DC electrical conductivity of carbon nanotube-polymer composites are studied with the aim of obtaining a complete list of design parameters that allow guarantying to the designer an increase in electrical properties of the composite by means of carbon nanotubes.

State Of Research

A novel class of carbon nanotube (CNT)-based nanomaterials has been surging since 1991 due to their noticeable mechanical and electrical properties, as well as their good electron transport properties. This is evidence that the development of CNT-reinforced polymer composites could contribute in expanding many areas of use, from energy-related devices to structural components. As a promising material with a wide range of applications, their poor solubility in aqueous and organic solvents has hindered the utilizations of CNTs. The current state of research in CNTs—both single-wall carbon nanotubes (SWCNT) and multiwalled carbon nanotube (MWCNT)-reinforced polymer composites—was reviewed in the context of the presently employed covalent and non-covalent functionalization. As such, this overview intends to provide a critical assessment of a surging class of composite materials and unveil the successful development associated with CNT-incorporated polymer composites. The mechanisms related to the mechanical, thermal, and electrical performance of CNT-reinforced polymer composites is also discussed. It is vital to understand how the addition of CNTs in a polymer composite alters the microstructure at the micro- and nano-scale, as well as how these modifications influence overall structural behavior, not only in its as fabricated form but also its functionalization techniques. The technological superiority gained with CNT addition to polymer composites may be advantageous, but scientific values are here to be critically explored for reliable, sustainable, and structural reliability in different industrial needs.

Carbon Nanotube Composite

In this paper, the carbon nanotube was well dispersed into the poly (3,4-ethylenedioxythiophene) poly (styrenesulfonate) (PEDOTPSS) solution with a best concentration of 4 mg/ml. The prepared sol was spun on poly (ether sulfone) (PES) substrates, showing sheet resistance as low as 19.8 Ω/sq and the high average transmittance over 90 %. The change in optical and electrical properties due to poly (ether sulfone) (PES) substrate was investigated to understand the failure mechanisms. For realizing the bending effect on electrical performance, the pre-deposited ZnO buffer was introduced to improve the deterioration during the repeated bending test. The composite polymer enhanced the electrical conductivity with less detrimental effect on the optical transparency, which suggests the potential transparent conductive films for use in developing optical and electrical device.
