Crumpled Graphene Nanosheets as Highly Effective Barrier Property Enhancers

摘要

In modern society, polymer packaging plays a critical role in the preservation and distribution of perishable goods such as food and prescription medicines. Since the effectiveness of polymer packaging materials in preventing product degradation is directly dependent upon their impermeability to degrada-tive gases and their opacity to high-energy light, significant efforts have been devoted to improving these properties. Herein, we report the exceptional ability of a graphene-based nanofiller to limit both oxygen permeation and light transmission in polymer films.
