From the author: The nanocomposite of polyamide 6 (PA6)/poly(methyl methacrylate) (PMMA)/carboxylic acid functionalized single walled carbon nanotubes (SWCNTs-COOH) was prepared in a weight ratio of 49.5/49.5/1 at 230[degrees]C by using melt-mixing method. The PA6/PMMA blend with weight ratio of 50/50 served as reference. The Fourier transform infrared analysis of nanocomposite shows the occurrence of hydrogen-bonding interactions among PA6, PMMA, and SWCNTs-COOH. Thermal studies of nanocomposite exhibited higher thermal stability and increased crystallinity of PA6 in nanocompo-site compared to the blend. The X-ray diffraction curve of nanocomposite indicates that the rich [[alpha].sub.11], phase of PA6 was higher compare to the blend. The scanning electron microscope analysis of nanocomposite confirmed that PMMA exhibited as a uniform dispersion and existed as co-continuous phase morphology in a continuous phase of PA6 compared to the blend. Furthermore, the obtained results suggest that the incorporation of SWCNTs-COOH into the PA6/PMMA blend enhances the compatibility as a compatibilizer between the two polymer components. POLYM. ENG.
