Electrohydrodynamic Direct-Write Orderly Micro/Nanofibrous Structure on Flexible Insulating Substrate

Figure 2

Micro/nanostructures deposited on PET insulate substrate under DC and AC electrical fields. (a) Nanofibers deposited on the PET substrate under the DC electrical field, experimental condition: 𝑈=4 kV, 𝐻=10 mm, 𝐶=14 wt%, and 𝑄=50 μL/hr; (b) nanofibers deposited on the PET substrate under the AC electrical field, experimental condition: 𝑈₋=−4 kV, 𝑈₊=4 kV, 𝑓_app=500 Hz, 𝜌=50%, 𝐻=10 mm, 𝐶=14 wt%, and 𝑄=50 μL/hr.
