Antistatic behavior of PAN-based low-temperature carbonaceous fibers

A kind of antistatic coatings which were applied to nonconductive surfaces were prepared with polytetrafluoroethylene (PTFE) paint as matrix, polyacrylonitrile (PAN)-based low-temperature carbonaceous fibers as conductive filler. The influences of carbonaceous fiber content, carbonization temperature, size and testing voltage on the surface resistivity of the coating were investigated. The surface resistivity could be well controlled in the static dissipative range (106-109 Ω) by changing the content, size and carbonization temperature of carbonaceous fibers. The present study could be useful for the application of chopped carbonaceous fibers in antistatic materials.
