Improving gas barrier properties of sugarcane‐based LLDPE with cellulose nanocrystals

Abstract

This study was aimed at improving the gas barrier property of sugarcane based LLDPE using cellulose nanocrystals (CNCs). Specifically, this study evaluated the effect of CNC content on the crystallinity, tortuosity factor, carbon dioxide permeability (P CO2 ), and/or oxygen permeability (P O2 ) of bio-LLDPE sheets and films. All nanocomposites showed considerable improvement in gas barrier irrespective of the CNC content. The P CO2 coefficient of LLDPE sheets

Fabrication of LLDPE based biodegradable composite incorporated with leather shavings and buffing dust: An approach for waste management

“…23 In a recent study, gas barrier property was improved by fabricating cellulose nanocrystals/LLDPE composites. 24 These above mentioned experiments did not consider waste materials while fabricating composite films. Hence, a novel strategy was taken to fabricate composite films from LS and LB combined with LLDPE.…”

Dispersibility Characterization of Cellulose Nanocrystals in Polymeric-Based Composites

“…178 Therefore, the transmittance can be used as an indicator of CNC dispersion in the matrix. 229 Geng et al found that the addition of CNCs did not affect the transmittance of the composite films, and all the obtained composites showed high transmittance, indicating the nanoscale dispersion of CNCs. 115 Several works have reported similar results.…”

“…In general, the addition of CNCs does not affect the transmittance of the composites when the CNCs are well dispersed, and their particle size is smaller than the wavelength of visible light (400–800 nm) . Therefore, the transmittance can be used as an indicator of CNC dispersion in the matrix . Geng et al found that the addition of CNCs did not affect the transmittance of the composite films, and all the obtained composites showed high transmittance, indicating the nanoscale dispersion of CNCs .…”

Evaluation of the Antibacterial Activity of Eco-Friendly Hybrid Composites on the Base of Oyster Shell Powder Modified by Metal Ions and LLDPE

“…One of them, linear low-density polyethylene (LLDPE), has decent impact resistance and tensile strength [ 41 ]. LLDPE has low crystallinity, which contributes to its excellent transparency [ 42 ]. LLDPE’s applicability is nonetheless constrained because it is a nonpolar polymer with an inert surface and low surface energy.…”
