摘要: Abstract The influence of ionic liquids on the structure and tensile properties (ILs)/polyamide 6 (PA6) specimens with different ratios was investigated by X-ray diffraction (XRD), differential scanning calorimetry (DSC), fourier transform infrared spectroscopy (FTIR) mechanical tests. results revealed that partial α crystalline form transformed to γ for ILs/PA6 specimens. melting temperature decreased increase ILs content. peak wavenumbers N-H stretching vibration C=O PA6 molecules reduced, while ascribed mixed motions C-N in-plane bending increased. Compared pure specimens, elongation at break improved in degrees.
