Abstract

Nowadays, cellulose nanocrystals (CNC) play a major role in industrial
processes due to their unique properties which, in turns, able to enhance the
physical properties of bulk materials. The interstice properties of CNC are vary
regarding to the source of the used cellulosic materials. The study aimed to
characterize cellulose CNC extracted from two different genotypes of cotton
slivers; Egyptian extra-long staple (G.88) and upland medium staple length (BF
FK37). As per acid hydrolysis, CNC was extracted from different genotypes of
cotton slivers by the use of H2SO4 60% (w/w) at 60 ℃ for 60 min. Then, the
extracted CNC was characterized by making used of different tools e.g.,
transmission electron microscopy (TEM), Dynamic Light Scattering (DLS), X-ray
diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, Thermo
Gravimetric analysis (TGA). Results revealed that, CNC was, successfully,
extracted by acid hydrolysis of cotton slivers. Notably, the size of the obtained
CNC was varied as genotypes of cotton slivers varies, which attained as shown
from TEM; the average dimensions (diameter × length) of 36.46 ± 7 nm × 355 ±
98.3 nm for extra-long staple, 37.2 ± 14 nm × 284 ± 83 nm for medium staple. This
fact was further supported by DLS as the size of extra-long staple was 22. 45 d.n
and 35.77 d.n for medium staple. In addition, XRD results demonstrated that, both
genotypes excited cellulose type I (crystalline polymorph). However, CNC
extracted from extra-long showed higher crystallinity index (80%) than observed
from medium staple. Moreover, the thermal stability observed for CNC of extra
long is significantly higher than obtained from medium. By varying of the source of
CNC, the size of the obtained crystals was varied besides crystallinity index and
their thermal stability properties. Therefore, the using of extra-long staple length
cotton slivers led to reduce the crystal size with improving in both crystallinity and
thermalproperties.
