title = "Ultrastrong graphene films via long-chain π-bridging",
abstract = "An inexpensive low-temperature process is demonstrated to fabricate resin-free, ultrastrong, supertough, and highly conductive graphene films with ultrahigh electromagnetic interference shielding capability via long-chain π-bridging. The graphene films have record in-plane strength as strong as cross-plied carbon fiber composites and much greater ability to absorb mechanical energy and resist property degradation during repeated severe mechanical deformations. The bioinspired interface design strategy can promote the conversion of natural graphite into high-performance graphene-based nanocomposites having promising applications in aerospace and flexible electronics.",
