چکیده مقاله:
Polymer nanocomposites are widely used in various industries due to their excellent mechanical, thermal and chemical properties. One of the special features of nanocomposite-reinforced with nanoclay is their high permeability properties. In order to increase the properties of nanoclay in the polymer substrate, an intercalate/exfoliate structure must be achieved. In this study, the structure of LDPE / nanoclay (Cloisite ۱۵A) nanocomposites with nanoclay ۵% wt were investigated to determine the effect of compatibilizer content and processing parameters such as mixing time and screw speed as variables. For this purpose, the response surface method (RSM) and two-level factorial design with three central points were used. X-ray diffraction (XRD) analysis was used to determine the distance between the platelets of nanoclay. The results showed that mixing time was the most effective parameter. In the case of the selected mixing time and screwspeed were at maximum and the compatiblizer cotent at the lowest level, a better dispersion of nanoclay was observed.
