Polymer composite application has risen significantly over the past decades. In general, the introduction of filler to the polymer matrix leads to sharp enhancement in the polymer property. However, the property of the polymer composite depends highly on the interaction between the filler and matrix. The properties of the polymer improve as the dispersion of the filler in polymer matrix increases. In order to achieve the best dispersion possible of filler in polymer matrix, the processing parameters should be selected carefully. In this project, high density polyethylene composites (HDPE-composites) were prepared using mini compounder. HDPE was mixed with organoclay (OC) and graphene (GR) separately. HDPE-composites, HDPE-OC and HDPE-GR, were morphologically characterized by SEM & XRD, and thermally and rheologically tested using DSC & TGA and Rheometer, respectively. Box-Behnken Design (BBD) with 3 levels was used as a design of experiment to investigate the effect of processing parameters on the thermal and rheological properties of the HDPE-composites. Factors investigated includes filler weight percentage (wt.%), mixing temperature and screw speed. The responses to be evaluated were melting temperature, crystallinity temperature, degree of crystallinity, degradation temperature, storage modulus, and complex viscosity of HDPE-composites. Analysis of variance (ANOVA) was done to evaluate the effect of each factor on the responses. Furthermore, the data obtained were used to fit to second order equation using MINITAB software to predict the responses. Constructed models were verified using validation experiments. Optimum processing parameters for the HDPE-OC were obtained as 1.474 wt.% of OC, mixing temperature of 183.2 °C, and screw speed of 76.5 rpm. On the other hand, using 0.32 wt.% of GR as a filler, mixing temperature of 172.3 °C, and screw speed of 91.3 rpm leads to the optimum values of HDPE-GR. The findings from this project will aid the polymer composite producers in select the optimum processing parameters, hence better polymer composite properties can be achieved.
