Exploring graphene origami-enabled metamaterials: A review

Auxetic metamaterials are a class of material with tunable Poisson's ratio. Nonetheless, most auxetics have weak mechanical properties, thus, implementing graphene origami (GOri) as a strong reinforcement can overcome this deficiency. This review explores the burgeoning field of auxetic metamaterials enhanced through the integration of graphene origami. This study also presents an in-depth investigation of the background of negative Poisson's ratio auxetic metamaterials, most importantly, graphene origami. Furthermore, it focuses on the notable mechanical characteristics such as increased flexibility, strength, and dynamic response of GOri-reinforced composites. Leveraging Hamilton's principle and other theoretical frameworks, this paper collates and examines the equation of motion derivations and the impact of various parameters on GOri behaviour.
