Effect of carbon black on triboelectrification electrostatic potential of MC nylon composites

The triboelectrification electrostatic potential (TEP) of neat MC nylon and MC nylon composites were investigated under dry sliding and dry rolling, respectively, and the effect of carbon black (CB) and mechanisms of anti-triboelectrification of composites were studied. The incorporation of CB with proper fractions made considerable contributions to reduce and stabilize the TEP and to control the electrical resistivity of composites. The TEP of neat MC nylon is easily influenced by friction operating parameters, while the external conditions almost have no influence on the TEP of composites. It is the conductive paths that play the dominant role in composites.
