Ultrasonic Assisted Extrusion of HDPE/clay Nanocomposites
High density polyethylene (HDPE) /clay (Cloisite-20-A) nanocomposites were prepared by using single screw compounding extruder with continuous treatment of ultrasound at different amplitude up to 10?m. The die pressure and power consumption due to ultrasound were measured at different feed rates of materials of various clay concentrations up to 10 wt%. Rheological, mechanical and thermal properties of ultrasonically treated and untreated nanocomposites were studied. X-ray diffraction (XRD) and transmitted electron microscope (TEM) were used to investigate the dispersion of clay and nanocrostructure of composites. The experimental results showed that sonication enhanced the dispersion during melt mixing of HDPE and clay.
