anocrystals (NCchit) and nanofibers (NFchit) extracted
from chitin are considered as nanomaterials of great
innovative potential and promising biomaterial for academic
and industrial fields. The research related to their production
and application is still new. In the other hand, in recent years,
many research programs have focused on developing more
and more bio-degradable packaging of natural polymers.
Among them, those based on polysaccharide polymers
such as hydroxypropylmethylcellulose (HPMC).This study is
the first to investigate the compatibility and reinforcement
effect of nano-size chitin fillers (NCchit and NFchit) on

Hydroxypropyl methyl cellulose (HPMC). NCchit aqueous
dispersions were prepared by acid hydrolysis of commercial
shrimp shell α-chitin while NFchit were prepared by mechanical
defibrillation using closed loop grinding. The average widths
and lengths of NFchit were (8.7 ± 3.17) nm (673.9 ± 263.3) nm
respectively while for NCchit were (9.7 ± 3.2) nm and (243.5±
55.1) nm. Composites of HPMC with different loadings of
NCchit or NFchit were prepared by casting technique, using
water as solvent. The effect of morphology and size of each
nanomaterial on morphology, transparency, mechanical, thermal
and barrier properties of the resulting nanocomposites were
investigated using various techniques. The obtained results
revealed the positive effect of both nanomaterials on HPMC by
enhancing its mechanical properties. The nanocomposite films
exhibited better oxygen and water barrier with slight decrease in
transparency than control HPMC film. Overall, chitin NCchit offer
superior reinforcing performance than chitin NFchit.
