Abstract
The effect of injection molding parameters (screw rotational speed, back pressure, injec-tion flow rate and hold- ing pressure) on the nanofiller dispersion of melt-mixed PP/clay nanocomposites was investigated. The nanocomposites containing 4 wt% clay were obtained by dilution of a PP/clay masterbatch into a PP matrix. The evaluation of the dispersion degree was obtained from dynamic rheological measurements. The storage modulus and complex viscosity exhibit signifi- cant dependence on the injection molding parameters. PP/clay nanocomposite molded using more severe injection parame- ters (high shear and long residence time) displays the highest storage modulus ...
