Influence of thermal treatment conditions on porosity development and mechanical properties of activated carbon cloths from a novel nanofibre-made fabric
Activated carbon cloths (ACC) were prepared from Tencel®, a novel regenerated cellulose nanofibre fabric, by phosphoric acid activation in an inert atmosphere using different thermal treatment conditions. The effect of the final thermal treatment temperature (663-963 °C) and temperature programme (t...

Activated carbon cloths (ACC) were prepared from Tencel®, a novel regenerated cellulose nanofibre fabric, by phosphoric acid activation in an inert atmosphere using different thermal treatment conditions.

Nitrogen isotherms at -196 °C, carbon dioxide isotherms at 0 °C, breaking loads and Youngs modulus values were determined for all the samples.
