Abstract: Aluminum mounts are ubiquitously present in scanning electron microscope (SEM) laboratories. They are an inexpensive light material with good conductivity properties, and are generally compatible with conductive adhesive products. In the course of using aluminum mounts to examine nanoscale materials, some compatibility issues were revealed. One limiting issue was charge conduction. Nanoscale materials can be a more efficient conductor of electrons than the aluminum mount with its layer of oxides. The design of the SEM can constrain charge dissipation. These topics are discussed in summarized form using examples from nanotube dispersion research.
