Counterion-Mediated Humidity Modulation of Electronic Transport in Pristine MWCNT/TOCNF Composites

Abstract Humidity-driven electrical responses in carbon-cellulose composites are commonly attributed to matrix swelling. However, in TEMPO-oxidized nanocellulose (TOCNF), water uptake also releases Na+ counterions from carboxylate residues, enabling interfacial polarization via i...
