AbstractHydrogen bonding in polyamide 66/clay nanocomposite (PA66CN) was first investigated with temperature Fourier transform infrared (FTIR), the results of which were compared with that of pristine polyamide 66 (PA66) with the same thermal history. FTIR spectra at room temperature revealed that there is essentially 100% hydrogen bonding in both PA66CN and PA66, and the difference in hydrogen-bonding status between them is tiny. Additionally, DSC showed that the crystalline degrees and melting temperatures of PA66CN and PA66 prepared by melt quenching are similar. However, the changes of hydrogen bonding with temperature in PA66CN and PA66 are different. As the temperature rose, the hydrogen bonding in PA66CN attenuated and dissociated considerably at a smaller rate than PA66. According to transmission electron microscopic morphology of PA66CN, we analyzed the effect of nanodispersion clay layers on the motion of a polymer chain and the thermal expansion of crystalline lamella for interpreting the observed phenomenon.
