Effect of multi-sized graphite filler on the mechanical properties and electrical conductivity

This research successfully fabricated conductive polymer composites (CPCs) prepared using multiple sizes of graphite filler (40, 100, 150, and 200 μm) that provided excellent network formation within the fillers and polypropylene matrix which further improved both electrical conductivity and flexura...
