Terbium Doping Improves Thermal Behavior in Conductive Nanocomposite, but Commercial Case Remains Unproven

Highlights

• Terbium-chloride-doped polyaniline/MWCNT nanocomposite showed three thermal degradation stages with residue reaching 52.43% at higher heating rates.
• EDX detected only 0.12% terbium, and no undoped control was included in the thermal dataset, limiting causal conclusions about terbium's role.
• Electrical conductivity, cycling performance, and commercial manufacturability remain entirely untested in this early-stage laboratory study.
• The research highlights terbium's potential beyond permanent magnets as a small-volume performance enhancer in advanced functional materials.
