I have prepared the polyacrylonitrile (PAN) and CNT electrospun membrance onto glass fabric.But the membrance is not attached on the glass fabric.How to solve this problem?
How to measure the electrical conductivity of the nano fiber mambrance?
The 2-point probe method will give you a combination of the fiber mat resistance and the contact resistance (where the probe contacts the fiber).
You can gold sputter contacts or apply silver paint to help minimize contact resistance.
To estimate the contact resistance, measure the resistance across varying probe spacing, then plot resistance vs. spacing length. The Y intercept should give you the contact resistance. See link below...
excuse me! when we want to measure electrical conductivity of nanofiber, we should make a pellet from nanofiber ? or we can measure electrical conductivity of nanofiber as thin film?
