Key insights into TEMPO-mediated oxidation of cellulose: influence of starting material

The present study investigates the intricate relationships between the properties of cellulose nanomaterials (CNMs) and the lignocellulosic feedstocks from which they are derived. The starting pulps, consisting of eucalyptus, pine, hemp, and sisal commercial bleached pulps where characterized, and l...

The resulting CNMs were extensively analyzed to assess carboxyl content, nanofibrillation yield, optical transmittance, and rheological and structural properties through methods including X-ray diffraction, X-ray photoelectron spectroscopy, solid-state 13C nuclear magnetic resonance, and sugar composition analysis post-acidic methanolysis.
