Abstract
Ultra-conductive copper (UCC) has an enormous potential to disrupt the existing electrical and electronic systems. Recent studies on carbon nanotubes (CNTs), a new class of materials, showed the ballistic conductance of electricity. Researchers around the world are able to demonstrate ultra-conductivity in micro- and millimeter-length sections using various processing techniques by embedding CNTs in the copper matrix. Although multiple methods promise the possibility of producing copper-based nanocomposites with gains in electrical conductivity, thus far, scaling up these results has been quite a challenge. We investigated a hybrid method of both hot-pressing followed by rolling in order to produce UCC wire. Cu/CNT billets of 1/10%, 1/15%, and 1/20% were hot-pressed and the conductivity results were compared to a hot-pressed pure copper billet. Our results indicated that this method is not a viable approach, as the gains in electrical conductivity are neutralized, followed by attenuation of the wire cross-section.
Highlights
Today, the world is heavily dependent on electricity in all aspects of life, from lighting a house to lighting the International Space Station and running a car on Earth to running a rover on Mars
As we have entered into new age of technology, where electricity and electronics are used almost in all aspects, better conductors that are capable of carrying higher currents and low resistance are in demand
We report the experimental findings of using a hybrid method developed in order to synthesize copper/carbon nanotubes (CNTs) nanocomposites with enhanced electrical conductivity
Summary
The world is heavily dependent on electricity in all aspects of life, from lighting a house to lighting the International Space Station and running a car on Earth to running a rover on Mars. As we have entered into new age of technology, where electricity and electronics are used almost in all aspects, better conductors that are capable of carrying higher currents and low resistance are in demand. Wei et al [8] recorded the ability of MWCNTs to carry electrical current of a magnitude higher than 109 A/cm at elevated temperatures of 250 ◦C They reported that nanotubes show no observable failure and no measurable change in the resistance detected. Nayfeh et al [11] reported electrical conductivity of 113% IACS by copper nanocomposites produced by using the die-casting method. These results encourage researchers in pursuit of developing nanocomposites that exhibit higher electrical conductivity. We report the experimental findings of using a hybrid method developed in order to synthesize copper/CNT nanocomposites with enhanced electrical conductivity
