Abstract
Model thermoplastic composites containing both micro and nano filler particles were prepared and their melt flow behavior investigated near the physical gel point or percolation threshold loading levels. The threshold loading level was found to be strongly correlated with the particles size of the fillers and independent of the extrusion shear rate. Since the processing and compounding of high-surface-energy nano-particle filled polymers is very complex and not well understood, this study demonstrated the validity and adequacy of percolation study of such composites in steady-state pressure-drive flows using capillary melt rheometer.
