英文摘要 | The crystals of n, n'-dicyclohexyl-2,6-naphthalenedicarboxamide (dc26ndca) and n,n'-dicyclohexyl-1,4-naphthalenedicarboxamide (dc14ndca) were selected as nucleating agents to induce the crystallization of isotactic polypropylene (i-pp). the influence of the crystal structures of the nucleating agents on the crystallization behaviors and morphologies was studied by means of differential scanning calorimeter, wide-angle x-ray diffraction, polarized light microscopy, and atomic force microscopy (afm). the results show that dc26ndca is a selective beta-nucleating agent for the i-pp crystallization, while dc14ndca only has a very weak alpha-nucleating effect for the i-pp crystallization. the dynamic growth processes reveal that i-pp crystals grow with different crystallization behaviors in the presence of the nucleating agents. the i-pp lamellar structures on the crystal surfaces of the nucleating agents were observed by afm in details, which suggested that the nucleating agents induced the epitaxial growth of the i-pp lamellae. |
