Three-dimensional Electrical Property Mapping with Nanometer Resolution

The conductivity behavior of MWCNT networks within the volume of polymer nanocomposite samples is analyzed with nanometer resolution in all three dimensions. It is demonstrated that close to but above the percolation threshold for electrical conduction most of the MWCNTs do not contribute to the con...

Description
Summary:The conductivity behavior of MWCNT networks within the volume of polymer nanocomposite samples is analyzed with nanometer resolution in all three dimensions. It is demonstrated that close to but above the percolation threshold for electrical conduction most of the MWCNTs do not contribute to the conductive network within the nanocomposite.
