Preparing ACB/UHMWPE Composite by PCS Process and its Electric Resistance-Temperature Behavior

Article Preview

Abstract:

Composite particles with ultra-high molecular polyethylene (UHMWPE) matrix core and acetylene black (ACB) shell were produced by particle composite system (PCS), and molded into conductive polymer composites. Morphology of these composite particles was investigated by SEM. Matrix particles were coated by ACB nanoparticles very well. Conductive networks of ACB in polymer composites were seen by SEM. The results of electrical behavior study show that the polymer composites exhibit low percolation threshold and its electric conductivity is less affected by temperature due to unusual ACB distribution. Related mechanism is discussed.
