Effect of coupling agent on the mechanical properties of flame retardant PP/ATH nanocomposites
Polymer nanocomposites containing polypropylene (PP) as the polymer matrix and nanofiller aluminium hydroxide (ATH) as the flame retardant filler were compounded with various loading of maleic anhydride grafted polypropylene, MAPP (0, 1, 2, 3, 5 wt %). All materials were mixed using melt mixing p...

| Summary: | Polymer nanocomposites containing polypropylene (PP) as the polymer matrix and
nanofiller aluminium hydroxide (ATH) as the flame retardant filler were compounded with various
loading of maleic anhydride grafted polypropylene, MAPP (0, 1, 2, 3, 5 wt %). All materials were
mixed using melt mixing process and were further prepared using an injection moulding machine.
The mechanical performances of the samples were characterized using tensile and impact tests.
Improvements were observed for the tensile and impact properties of the PP/ATH samples after
being loaded with MAPP. MAPP loading of 1 wt % was determined to be the optimum content of
coupling agent addition as this loading enabled the best performance of the nanocomposite in
tensile and impact tests. Different morphologies of the fracture surfaces for all samples were
characterized using FESEM analysis. |
