Preparation of Lignocellulose Nanocrystals and Its Application in PVA Nanocomposite Films for Food Packaging Materials |
초록 |
Lignocellulose nanocrystals (LCNC) with various lignin content were successfully prepared from oak wood using two stage pretreatments followed by a concentrated sulfuric acid hydrolysis. LCNC samples was introduced into a polyvinyl alcohol (PVA) matrix to produce bio-nanocomposites at 10% and 50% mass ratio. With increasing of lignin content and mass ratio of LCNC samples on the nanocomposite exhibited improved UV-shielding properties, thermal stability, tensile strength, and hydrophobicity compared with the pure PVA matrix. Almost 100% of UV transmission was blocked by the PVA/LCNC 50 wt% bio-nanocomposite containing 24% lignin and its water contact angle increased remarkably from 21.9o to 96.7o. This study shows a promising nanocomposite film for food packaging. |
