Abstract

There is growing interest in cellulose nanofibres from renewable sources for several industrial applications. However, there is a lack of information about one of the most abundant cellulose pulps: bleached Eucalyptus kraft pulp. The objective of the present work was to obtain Eucalyptus cellulose micro/nanofibres by three different processes, namely: refining, sonication and acid hydrolysis of the cellulose pulp. The refining was limited by the low efficiency of isolated nanofibrils, while sonication was more effective for this purpose. However, the latter process occurred at the expense of considerable damage to the cellulose structure. The whiskers obtained by acid hydrolysis resulted in nanostructures with lower diameter and length, and high crystallinity. Increasing hydrolysis reaction time led to narrower and shorter whiskers, but increased the crystallinity index. The present work contributes to the different widespread methods used for the production of micro/nanofibres for different applications.

  • Acid hydrolysis and enzymatic hydrolysis are the most commonly employed methods for cellulose nanoparticle isolation.

    “Acid hydrolysis (Lu & Hsieh, 2012;Tonoli et al., 2012;Zuluaga et al., 2009) and enzymatic hydrolysis (George, Ramana, Bawa, & Siddaramaiah, 2011;Hassan, Mathew, Hassan, & Oksman, 2010;Pääkko et al., 2007;Satyamurthy, Jain, Balasubramanya, & Vigneshwaran, 2011;Woehl et al., 2010) are the most commonly employed methods.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
