Copper/Carbon Nanotube Ultraconductive Wire: Conduction, Processing, and Stability
Abstract
Task 1: Benchmark the status quo - The goal of Task 1 is to screen currently available UCC (untraconductive copper) samples with standardized methods in order to create a benchmark database. Task 2: Enhancing conduction – This work will focus on two key elements in achieving a UCC are to: a. Optimize the conductivity of the CNTs, and b. Optimize the electronic interaction between carbon nanotubes (CNTs) and the Cu matrix. Task 3: Achieving reproducible processing - The incorporation of CNTs into a Cu matrix requires an understanding of the microstructure of the hybrid and the distribution of the CNTs. Processing is believed to have a major effect on the efficacy of UCC wires. UCC wires will be produced by both traditional industry–based melt filament extrusion of Cu/CNT mixtures and new methods that will enhance dispersion. Task 4: Ensuring stability – stability of the carbon/copper conductors over time will be assessed through study of the Cu/cargon galvanic interactions and evaluation of the wires using potentiodynamic tests to assess the change in behavior of cathodic and anodic processes.
