Abstract
The SBR film including a carbon black(Ketjen black, Denka black or Vulcan XC-72) was made from the compounds of SBR latex and carbon blacks of several weight %. The carbon black incorporated SBR rubber(CB-SBR) film were investigated in terms of resultant morphology and electrical properties. Up to The loading level 10wt%. the specific resistivity of the CB-SBR nim was decreased as the content of carbon black was increased. Of the three carbon blacks Keljen black endowed the highest conductivity on the CB-SBR rubber nim at the same loading level. On the whole, the antistatic effect was observed from the loading level 2.5~5.0wt% by towering the specific resistivity below 108$\Omega$.cm, and loading the carbon black more than 10wt% gave rise to conductivity by lowering the specific resistivity below 104$\Omega$.cm. Among the carbon blacks Kctjen black gave the highest antistatic efficiency, followed by Denka black and Vulcan XC-72.
