AB - Constructing high-density single-walled carbon nanotubes (SWCNTs) network assemblies is essential for improving their electrical conductivity. However, controlling the nanoporosity, including specific surface area (SSA) and pore structure, is critical for maintaining reversible capacity in CNT-based energy storage systems. In this study, we investigated a solution-based strategy using acid and surfactant treatments to enhance the electrical conductivity of SWCNT networks while minimizing changes in nanoporosity. HNO3/H2SO4 acid treatment and sodium dodecyl benzene sulfonate (SDBS)-assisted dispersion were applied to form uniform, densely packed SWCNT assemblies. Acid treatment increased the SSA from 246 to 732 m2 g⁻1 and the micropore volume from 0.06 to 0.28 mL g⁻1. In contrast, SDBS treatment moderately increased the SSA (246 to 350 m2·g⁻1) with minor changes in meso/microporosity and preserved the overall pore structure well. In addition the electrical conductivity increased by a factor of 3.5 after acid treatment and by a factor of 6 after SDBS treatment, reaching 1.39 × 105 and 2.36 × 105 S m⁻1, respectively. These results demonstrate that SDBS treatment, via surfactant-driven reassembly, offers a simple, scalable, and structure-preserving strategy to tailor nanoporosity and enhance the performance of SWCNT-based electrochemical devices.
