Functionalized Graphene Reinforced Thermoplastic Nanocomposites as Strain Sensors in Structural Health Monitoring (Preprint)

摘要

Functionalized graphene-polyvinylidene fluoride (f-G-PVDF) nanocomposite films were synthesized using simple solvent casting technique. The investigation demonstrates the real time strain response of f-G-PVDF nanocomposite on macro scale under tensile loads and the use of this nanocomposite as 10 strain sensor. This is ascribed to the variation in electrical properties of graphene in the polymer upon mechanical deformation at the nanoscale.
