摘要：
The hyperbranched polyamide 6(PA6)/montmorillonite(MMT) nanocomposites were prepared by the in-situ polymerization. Using automatic viscosity tester, Fourier infrared spectrometer, thermogravimetric analysis, differential scanning calorimeter, X-ray diffraction, capillary rheometer, universal testing machine instrument,the hyperbranched PA6/montmorillonite nanocomposites were characterized. The results show that the rheological curves of shear viscosity and shear rate of the nanocomposites are in line with the characteristics of power-law fluids, which is convenient for shaping. The crystals (α,γ) of composite materials are changed since they are added to MMT and their crystallinity is reduced from 36.49% of pure hyperbranched PA6 to 33.54%. In addition, with the addition of MMT into the matrix, the thermal stability, tensile strength, elongation at break and impact strength of nanocomposites increase significantly. © 2019, Editorial Board of Polymer Materials Science & Engineering.
