Abstract
Approaches for implementing a conductive gasket comprising carbon nanotubes for deployment within a sensitive environment, such as an environment containing equipment whose operation may be affected by airborne particles or electromagnetic energy. For example, a hard-disk drive (HDD) comprises an enclosure that is formed by coupling a first component, such as a cover, to a second component, such as a base, using one or more gaskets. The one or more gaskets may be constructed using a material that includes carbon nanotubes. The composition of the material used to construct the gaskets may be selected to achieve a desired electromagnetic conductivity for the gaskets. In this way, the gaskets of the enclosure of the HDD do not render the enclosure vulnerable to external electromagnetic energy and are constructed in a manner that does not introduce any harmful airborne contaminants within the protective enclosure of the HDD.
