제목 Hierarchically Architectured 3D graphene Assembly as Strain Sensor
초록 Nowadays, recent development in designing graphene-based 3D structure shows new possibilities for various applications. Most of them are prepared by means of random self-assemblies of graphene oxide or graphene nanosheets via direct freeze-drying or hydrothermal processes, and direct template chemical-vapor-deposition. These methods have created the large-scale 3D structure like Graphene oxide aerogel, but, it is still challenging to generate well-defined 3d regular graphene structure. To overcome this limitation, we use microfluidic system for generating building blocks to generate 3D hierarchical graphene structures. After reduction process, building blocks are transformed into 3D well-defined interconnected network structures with having electrical conductivity. Then, the resulting 3D closed-cellular structure serves as the strain gauge. And the strain gauge exhibited the gauge factor of around 4 and it shows excellent mechanical reversibility over 250cycles.
