Ipzz-266

Four‑point probe measurements gave σ_elec = 1.8 × 10⁻² S cm⁻¹ at 25 °C, increasing to 4.5 × 10⁻² S cm⁻¹ at 60 °C. Variable‑temperature conductivity obeyed an Arrhenius law (E_a ≈ 0.09 eV), reflecting thermally assisted hopping along the conjugated thiophene segments.

Being a production by SOD, the technical quality is high. IPZZ-266
