摘要：
In this study, we describe the preparation and characterization of natural rubber nanocomposites filled with poly (methyl methacrylate) grafted multiwalled carbon nanotube. The use of various filler loadings (1, 2, 3, and 5wt %) and melt blending method was employed. From the results, nanocomposite with 1 phr filler loading showed the optimal tensile strength of 4.92 MaP, while that of the carbon black N330 filled natural rubber with similar filler loading found to be 2.48 MaP. The nanocomposite with optimal tensile strength exhibited a good filler dispersion in the natural rubber matrix, which was depicted by the field emission scanning electron microscopy images. The thermal degradation temperature of the vulcanized neat natural rubber composite was increased from 380 degrees C to 462 degrees C with 1 phr filler loading. The polymer modified multiwalled carbon nanotube improved the mechanical and thermal properties of natural rubber, suggesting its potential as reinforcement filler in rubber industry.
