Structural, morphological, and dynamic mechanical properties of Zn‐filled Nylon 11

Abstract

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.

Achieving efficient and large-scale preparation of mesophase-nylon 11 film by random copolymerization of nylon 11 and nylon 611

“…All the characteristic absorption peaks of aliphatic nylon displayed in infrared spectrum: 3299 cm À1 (N-H stretching), 2918 and 2850 cm À1 (-CH 2stretching), 1633 cm À1 (amide I, C]O stretching), 1541 cm À1 (amide II, combined absorption peak of C-H stretching and N-H bending), 1278 cm À1 (amide III, C-N stretching), 721 cm À1 (in-plane oscillation absorption peak of -(CH 2 ) n -, n $ 4). 1 H NMR spectrum further approved that the synthesized product is random copolymer of PA11 and PA611, as shown in Fig. 1b The isomorphic crystals of nylon random copolymer…”
