Nylon 11 samples were filled with metal (Zn) fillers of two different concentrations (1 and 5% w/w) each. The samples in the form of disc were obtained by using hot press molder. The structural properties have been investigated using density measurement and wide angle X-ray diffraction (WAXD) technique. The morphology of pure and Zn-filled samples has been studied using scanning electron microscopy. Glass transition (T-g) temperature was determined using dynamic mechanical thermal analyzer (DMTA). The result shows that there is slight crystal modification due to the addition of metal fillers (Zn), and the crystallinity has improved. (c) 2006 Wiley Periodicals, Inc.
