Speech Title: Graphene Origami Enabled Mechanical Metamaterials for Engineering Structures
Abstract: Mechanical metamaterials with negative Poisson’s ratio (NPR), negative thermal expansion (NTE), etc. are of great significance in engineering applications. Majority of the metamaterials reported so far, however, are not materials but structures that are either mechanically weak or heavily reliant on specifically designed architecture/topology. Consequently, their metamaterial performance may be significantly deteriorated or even lost due to local structural deformation or failure under excessive external loading. Developing materials simultaneously possessing metamaterial characteristics and excellent mechanical properties poses a great challenge. This talk reports the latest development of a class of novel graphene origami-enabled mechanical metamaterials with a highly tunable NPR/NTE as well as improved mechanical properties. The research findings open a new avenue to develop graphene reinforced nanocomposite structures that are auxetic, light yet very strong.
