Eco-friendly PVA–chitosan nanocomposite hydrogels reinforced with nanocellulose and crosslinked by vanillin: fabrication, characterization, and biodegradability
The use of biodegradable materials in food packaging has gained increasing attention as a sustainable alternative to conventional plastics. In this study, calcium chloride-loaded nanofilms were developed using sodium alginate (NaAlg) as the primary polymer matrix, with chitosan (Ch) added at varying concentrations, res...

In this study, dual-crosslinked calcium alginate-nanocrystalline cellulose (CaAlg-NCC) bio-nanocomposite films were synthesized via a two-step gelation method. NCC, prepared by acid hydrolysis of microcrystalline cellulose (MCC), exhibited 79% crystallinity and a zeta potential of -32.14 mV at pH 5.8, and was incorpora...

The present study deals with polypropylene (PP) nanocomposites reinforced with multi‐walled carbon nanotubes (MWCNTs) and reduced graphene oxide (RGO). A constant low filler loading of 1.5% was used individually and in hybrid combinations with different ratios. Twin‐screw extrusion was utilized to fabricate the PP na...
Polylactic acid (PLA) and polyvinyl acetate (PVAc) blends show promise for sustainable packaging, although their limited thermo‐mechanical strength and absence of antimicrobial functionalities, restrict their wide applications. This study focuses on the development and characterization of PLA/PVAc‐based nanocomposi...
