suspension was adjusted to a constant rate of 0.3mL/h using
a syringe pump. A piece of aluminum foil was placed 15 cm
below the tip of the needle to collect the as-spun nanofibers.
Finally, the PLA/PU/GO fibrous paper was obtained by
removing residual solvents at room temperature and peeling
from the foil. Also, PLA/PU nanofibrous paper was prepared
under the same conditions
