Ultrastrong Graphene Films via Long-Chain π-Bridging

Converting natural graphite to high-performance graphene films is very attractive due to graphite's abundance. However, this conversion is challenging to do inexpensively and under ambient conditions. One of the major challenges is how to design the interface between adjacent graphene nanosheets to integrate high strength, high toughness, and high conductivity into graphene films. Here, we demonstrate that a long-chain π-π bonding agent can...
