How to calculate potential difference between two triboelectric surfaces

Please login with a confirmed email address before reporting spam

Hello everyone,

I want to find the potential difference between two triboelectric surfaces (PDMS & AL) arranged vertically. Aluminum is used as an electrode and triboelectric surface.

I want to use this equation V = σ x(t) /ε0

V=potential difference, σ= surface charge density (1 μC/m2) , x(t)= distance between the surfaces, ε permitivity.

I want to vary the gap distance between the surfaces and check their effect on potential difference.
I want the result like shown in the attached image
Thanks in advance
