文摘
- •
Homogeneous mobile PVA/GO dispersions without gelation were successfully obtained.
- •
Continuous PVA/RGO hybrid fibers were produced by spinning and chemical reduction.
- •
The hybrid fibers shows obviously higher toughness, hydrophilicity and capacitance.
- •
A yarn supercapacitor was assembled and exhibits an energy density of 5.97 mW h cm−3.
- •
The supercapacitor is flexible and robust enough to be weaved into a textile.
