Barrier properties and structural study of nanocomposite of HDPE/Montmorillonite modified with polyvinylalcohol

"In this work was studied the permeation of CO2 in films of high-density polyethylene (HDPE) and organoclay modified with polyvinylalcohol () obtained from melt blending. Permeation study showed that the incorporation of the modified organoclay generates a significant effect on the barrier prop...
