Area of Science:

• Materials Science
• Electrical Engineering
• Nanotechnology

Background:

• Triboelectric nanogenerators (TENGs) are known for high voltage, low current output.
• Expanding TENG applications is a key research area.
• Electrospinning requires high voltage to fabricate nanofibers.

Purpose of the Study:

• To design and demonstrate a self-powered electrospinning system using a TENG.
• To achieve high direct voltage output for electrospinning via a TENG-based system.
• To fabricate various polymer nanofibers using the developed self-powered system.

Main Methods:

• A rotating-disk TENG (R-TENG) was designed and integrated with a voltage-doubling rectifying circuit (VDRC).
• The R-TENG generated alternating voltage up to 1400 V.
• The VDRC boosted the voltage to a maximum constant direct voltage of 8.0 kV.

Main Results:

• The self-powered electrospinning system successfully fabricated polymer nanofibers from PET, PA6, PAN, PVDF, and TPU.
• The system demonstrated stable operation powered solely by the TENG.
• The high voltage output from the TENG-VDRC system was sufficient for effective electrospinning.

Conclusions:

• TENGs can be effectively utilized as a power source for high-voltage applications like electrospinning.
• The developed self-powered electrospinning system offers a novel approach for nanofiber fabrication.
• This work broadens the application scope of TENGs in advanced material manufacturing.
