Methods and apparatus for measuring the electrical properties of nanofibers

Abstract

The present disclosure provides a method and apparatus for measuring the electrical properties of nanofibers, comprising: placing and connecting nanofibers and a working electrode in a cathode chamber; adding a saturated salt solution to the cathode chamber; placing a reference electrode and a counter electrode in an anode chamber, ensuring that the cathode and anode chambers are independent of each other; adding an anolyte to the anode chamber to completely immerse the electrodes within it; introducing cathode and anode atmospheres into the cathode and anode chambers respectively; measuring the voltage difference between the working electrode and the reference electrode until it stabilizes, thereby achieving a target atmosphere in the cathode and anode chambers; adjusting the temperature in the cathode and anode chambers to a target temperature; adjusting the humidity in the cathode chamber using the saturated salt solution, during which the working electrode is excited; measuring the electrochemical impedance of the nanofibers until it stabilizes, thereby achieving a target humidity in the cathode chamber; and measuring the electrical properties of the nanofibers under the target atmosphere and humidity conditions. This disclosure ensures the stability and accuracy of the measurements, providing support for resolving the structure-property relationship of nanofibers.
