For every three people on the planet there is approximately two Tonne (Te) of available plastic waste. We show that carbon recovery from polystyrene (PS) enhanced by co-addition to solvents grow nanotubes (CNTs) liquid injection chemical vapour deposition. Polystyrene was loaded up 4 wt% in toluene and heated 780 °C presence a ferrocene catalyst hydrogen/argon carrier gas 1:19 ratio. High resolution transmission electron microscopy (HRTEM), scanning (SEM), thermogravimetric analysis (TGA) Raman spectroscopy were used identify multi-walled (MWCNTs). The PS addition range 0 showed improved quality CNT homogeneity; “Graphitic/Defective” (G/D) values increased 1.9 2.3; mean diameters 43.0 49.2 nm; maximum yield 11.3% 14.2%. Since both percentage with respect addition, we conclude contributes within MWCNTs. electrical contact resistance acid washed Bucky papers produced each loading, ranged 2.2 4.4 Ohm, no direct correlation loading. Due this narrow range, materials different loading mixed create six wires an Ethernet cable tested using iPerf give uplink downlink speeds ~99.5 Mbps, comparable Cu wire identical dimension (~99.5 Mbps). lifecycle assessment (LCA) production compared copper for use case Boeing 747-400 over lifespan craft. their lightweight nature decreased CO2 footprint 21 kTonne (kTe) aircraft lifespan.
