Amorphous perfluoroalkenyl vinyl ether polymer devices store significant electric charge due to quantum-size effects in nanometre-sized cavities. These novel polymer devices demonstrate potential for energy storage applications, illuminating an LED after charging.
Area of Science:
- Materials Science
- Electrical Engineering
- Polymer Science
Background:
- Amorphous polymers with nanometre-sized surface cavities exhibit unique electrical properties.
- The quantum-size effect influences charge storage capabilities in nanoscale materials.
Purpose of the Study:
- To investigate the charge storage capacity of amorphous perfluoroalkenyl vinyl ether polymer devices.
- To analyze the electrical characteristics and potential applications of these polymer devices.
Main Methods:
- Fabrication of amorphous perfluoroalkenyl vinyl ether polymer devices.
- Electrical characterization using Nyquist and Bode diagrams.
- Analysis of constant current discharging behavior and surface area effects.
Main Results:
- Devices exhibit a high work function (approx. 10 eV) and distinct electrical signatures (near-vertical Nyquist, horizontal Bode phase angle).
- An integrated surface area effect was observed during constant current discharging.
- The polymer device successfully illuminated a red LED for 3 ms after charging.
Conclusions:
- Amorphous perfluoroalkenyl vinyl ether polymers are capable of storing substantial electric charge.
- The observed phenomena can be attributed to a distributed constant electric circuit model.
- Potential for enhanced energy storage through integration with micro-electro mechanical systems (MEMS).
