Abstract Microcrystalline cellulose/nano-SiO2
composite films have been successfully prepared from
solutions in ionic liquid 1-allyl-3-methylimidazolium
chloride by a facile and economic method. The
microstructure and properties were investigated by
Fourier transform infrared spectroscopy, wide-angle
X-ray diffraction, scanning electron microscopy,
transmission electron microscopy, water contact
angle, thermal gravimetric analyses, and tensile testing.
The results revealed that the well-dispersed
nanoparticles exhibit strong interfacial interactions
with cellulose matrix. The thermal stability and tensile
strength of the cellulose nanocomposite films were
significantly improved over those of pure regenerated
cellulose film. Furthermore, the cellulose nanocomposite
films exhibited better hydrophobicity and a
lower degree of swelling than pure cellulose. This
method is believed to have potential application in the
field of fabricating cellulose-based nanocomposite
film with high performance, thus enlarging the scope
of commercial application of cellulose-based
