Abstract | The research and development of functional polymer composites and their production have posed significant challenges, particularly in creating high mechanical strength and thermal stability composites. In this study, we utilized a micro corotation extruder and injection molding to produce covalently functionalized Indian bentonite clay-nylon 6 high-strength nanocomposites. For comparison, two different amines, 3-aminopropyl trimethoxysilane and N-[3-(trimethoxysilyl) propyl] ethylene di-amine, were used to functionalize bentonite clay. Additionally, 3% and 5% less amino clay filler was added in the nanocomposite to manufacture the polymer composite. Analytical techniques such as Powder X-Ray Diffraction, Fourier transform infrared, thermal gravimetric analysis, and Brunauer-Emmett-Teller surface area were used to characterize the molecular orientation of amine functionalization on clay minerals. Wide-angle X-ray diffraction, atomic force microscopy, and transmission electron microscope were used to characterize the nylon 6 intercalated in amino clay nanocomposite and the polymer structure morphology. Thermogravimetric analysis and differential scanning calorimetry were used to investigate the crystalline thermal behavior of clay-nylon 6 composites. From the results, it was observed that the composition containing 5 wt.% amino clay demonstrated a significant improvement in tensile strength when compared with the composition containing 3 wt.% amino clay. The mechanical strength and the thermal behavior showed a significant improvement of similar to 200% for 5% amino clay-nylon 6 nanocomposite. |
