At a forecasted 6.6% CAGR from 2024 to 2030, the carbon nanotubes market is set to grow steadily, but the research signal is anything but uniform. One study reports conductive nanocomposites reaching percolation at just 0.1 wt% CNT, while other formulations push toward 30 wt% to hit a specific conductivity threshold, and still others report performance boosts like 60% lower oxygen permeability. We pulled together the key industry, materials, processing, and regulation figures to show why CNT outcomes can swing so widely.
