Theoretical Properties of Mag-Carbyne: A Lighter, Stronger Alternative to Magmatter Nanotubes
This manuscript investigates the theoretical properties of one-dimensional mag-carbon polymers, specifically mag-carbyne, as a lighter-weight alternative to the previously studied mag-carbon nanotubes (mag-CNTs). While mag-CNTs exhibit unparalleled absolute strength, their substantial linear mass density ($\approx 12.8 \text{ kg/m}$) presents a challenge for mass-critical applications. This work explores if a 1D polymer analogue can offer a superior strength-to-weight ratio. By applying a rigorously derived, carbon-specific scaling methodology to carbyne, theoretically the strongest 1D material, we calculate the properties of its magmatter counterpart. ...
