Abstract
A compound containing 75 wt% of high-density polyethylene (HDPE) and 25 wt% of polypropylene (PP) was melt-mixed in an extruder. The resulting compound was fibrillated by drawing it through a pair of steel rollers at 138°C. The fibrillated tape was cut into small pieces and then re-molded at temperatures above the melting point of HDPE. TEM results indicate that PP fibrils of about 30–150 nm in diameter were created in the HDPE matrix. The mechanical properties of HDPE were greatly improved with a yield stress above 60 MPa and a Young modulus of 3.5 GPa.
