Abstract
Conventional toughening is achieved by the incorporation of elastomers into epoxy, leading to a loss of rigidity and decrease of thermal properties. In addition to elastomers, rigid fillers including silica and clay have been employed for improving toughness without sacrificing rigidity. However, rigid additives cannot effectively stabilize and stop crack propagation.
Over the past two decades, carbon nanomaterials have been extensively studied, including fullerenes, nanofibers, and nanotubes. Atomically thin graphene is now hailed as the latest rising star ...
