Impermeability of Oxygen in Passive/Active Polyethylene Nanocomposite Films, Ph.D. Dissertation Sharif University of Technology ; Bagheri, Reza (Supervisor) ; Shojaei, Akbar (Supervisor)
Abstract
In this study, polyethylene films made of LDPE / LLPE / reinforced with mechanical barrier of clay and reactant of iron nanoparticles were made in their optimal combination and necessary improvements were made on them. Investigations show that, independent of volume fraction, the addition of spherical nanoparticles does not have much effect on reducing the polymer matrix’s permeability. In nanocomposites containing cylindrical particles, for considerable reduction of the permeability, over 20 volume percent of nanoparticles it is required, while in platelet nanoparticles, less than 10% vol is sufficient. In clays with modifier concentration above the cation exchange capacity, there is less...
