Preparation of Cellulose Nanocrystal Aerogel from Wastepaper through
Freeze-drying Technique

Cellulose nanomaterials processing for aerogel preparation has received considerable
attention among the scientific community due to its fascinating properties. In this work, we report
on the preparation of cellulose nanocrystals (CNCs) aerogel from wastepaper using a freeze-drying
technique. Structural analysis of the cellulosic particles extracted was investigated by Fourier
Transform Infrared Spectroscopy (FTIR). Morphological analysis of the extracted cellulose and
CNCs were carried out by Scanning electron microscopy (SEM) and Transmission electron
microscopy (TEM) respectively. We achieved density of aerogel down to 0.012 g/cm3 which is
comparable with typical values of cellulosic aerogels. The preparation of the CNCs aerogel might
offers a wide range of aerogel applications through an environmentally friendly conversion of
wastepaper material.
