A flexible and transparent gas barrier remains a key challenge for high performance food and flexible electronics packaging. A transparent nanobrick wall of graphene oxide nanoplatelets and polyethylenimine (< 100 nm thick), deposited using the layer-by-layer assembly technique, reduces the oxygen permeability of PET film by orders of magnitude, as reported by Jaime C. Grunlan and co-workers on page 503. The cover image, by graphic designer David Feagan, conceptually highlights the ability of this nanobrick wall to block the passage of oxygen.
