Electrical Conductive Materials templated from elastic rubber platforms

Highly stretchable and conductive three-dimensional (3D) micro-wrinkled reduced graphene oxide (MWrGO) film was fabricated using a novel thermo-mechanical shrinking method from elastic rubber materials. This 3D rGO architecture not only increases the specific area for more electrons to pass through but also bestows stretchability to the conductive pathway. The structural change of micro-wrinkles during the deformation had been monitored by an in-situ straining microscopy. The electrical conductivity of the samples remained fairly stable and stayed above 25 S/cm under low deformation (no more than 30 % strain) for up to 500 mechanical stretching-release cycles. The isotropic MWrGO/PDMS composite can be stretched bi-axially. This MWrGO based stretchable composite with stable electrical properties and long life span could form a new platform for stretchable electronics.
