Sh. Djumagulov¹, B. Umarov¹, A. Khamidov², O. Ruzimuradov², A. Kenjaev³

In this study, nanocomposite materials based on titanium dioxide and polymethylene naphthalene sulfonate (PMNS) were investigated. The main objective was to evaluate the enhancement in ionic conductivity of the synthesized TiO₂/PMNS nanocomposites. Key structural parameters—including nanotube diameter, wall thickness, and pore spacing—were measured and statistically…
