Shear-flow-induced graphene coating microfibers from microfluidic spinning
The advancement in flexible electronics calls for the invention of fiber-based electronic systems by either surface modification or encapsulation. Here, we present novel shear-flow-induced graphene nanosheets coating microfibers by integrating the dip-coating approach with the microfluidic spinning method. The core hydrogel microfiber was firstly continuously spun from the microfluidic device, and the shear-flow from the dip-coating approach allowed the formation of the thin graphene oxide (GO) nanosheets coating shell.
