ELECTROMECHANICAL CHARACTERISATION AND APPLICATION OF GRAPHENE AEROGEL/POLYMER COMPOSITES

Overall, this work has provided much insight into the relationship between the graphene sheet and cellular assembly architecture and the resulting dynamic electromechanical properties of ultralight graphene aerogel (UGA)-based composite materials and developed a new UGA/PDMS composite architecture that provides frequency-independent electromechanical property. Challenging the traditional notion that polymer-based materials are too viscoelastic to detect instant and high-frequency deformations, this work found that such materials can indeed be used for broadband frequency deformation detections. This achievement is expected to advance the future development and utilization of flexible polymer electronics in entirely new research and industry fields.
