xii, 81 p. : ill. ; 30 cm. + 1 CD-ROM In this research, the influence of auto-thermal extrusion on the thermal stability and morphology of fabricated polyamide6 (PA6) nanocomposites with varying clay loading and screw speed is discussed. The effect of zero-heat transferred extrusion systems on the thermal degradation rate of organic polymer and inorganic nanoclay is the main focus of this research. A polymer nanocomposite based from polyamide 6 and Cloisite® 20A, commercialized organic modified nanoclay, was prepared by using auto-thermal and conventional melt extrusion system. The morphological characteristics were determined through the application of X-ray diffraction (XRD) and scanning electron microscope (SEM). The thermal stability of compounded PA6/C20A nanocomposite was conducted using thermogravimetric analysis (TGA). The clay content and screw speed of the extruder dictates the quality of the PA6/C20A nanocomposites as well as the auto-thermal or conventional extrusion system itself. The auto-thermal extrusion affects the thermal stability of the melt-processed polymer nanocomposites by allowing even distribution of heat energy throughout the molten compound. However, it has very little effect on the morphology structure of PA6/C20A nanocomposites. As an addition, the screw speed of the extruder also affects the onset degradation temperature of samples produced. specialized Geraldine Chan Sue Ching Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang – 2013 Bibliography : p. 68-73 Extrusion process Nanocomposites (Materials) Polymers Deterioration Clay THE0002157(Local) UMP 131112 20251114204550.0 vtls000075939
