Spreading current on polymer surface

Scanning Spreading Resistance Microscopy (SSRM) on the surface of carbon black-silicon rubber composite. The left image is topography (contact mode), the right image is distribution of the current for the same area. The carbon black forms conductive net inside the silicon rubber matrix. By using conductive tip we can find places where this net appears on the matrix surface.
