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.
