Thermal/ Dynamic Mechanical, and Barrier Studies of Potassium Permanganate-LDPE Nanocomposites

摘要

This study investigated nanocomposites based on low density polyethylene containing 2, 3, 5 and 7 wt potassium permanganate (KMnO4) nanoparticles as a new novel material used for film packaging in fruit industry. This work included preparation and modification of nano-KMnO4,fabrication and characterization of the nanocomposites. Presence of filler caused reduction in degree of crystallinity that was confirmed by WXRD and DSC analysis. Barrier properties of nanocomposite against oxygen were improved up to 24.
