PCS (particle composite system) is a kind of dry coating equipment. The PCS process involves encapsulating UHMWPE (ultra-high molecular polyethylene) particles with a layer of SCB (super conductive carbon black) or ACB (acetylene black), and subsequently compacting these CB-encapsulated UHMWPE powders by compression molding to manufacture conductive polymer composites respectively. Morphologies of these composite particles were investigated by SEM. By SEM, we can see the conductive networks of CB in polymer composites. Coating-molding process with PCS can be used to form network structure in ceramics and metal as well.
