Abstract
AbstractVariable‐temperature Fourier transform infrared spectroscopy was used to investigate matrix–nanofiller interactions in amorphous semiaromatic polyamide/layered silicate nanocomposites prepared by melt intercalation. The types of polymer–nanofiller interactions were found to be strongly dependent on the nature of the polymer matrix and the surfactant‐modified layered silicate. Improved compatibility resulted when hydrogen‐bonding interactions occurred between the surfactant and polymer chains. The presence of surfactants with phenyl groups also led to a more stable molecular structure of the polymer matrix because of the enhanced resonance effect between aromatic groups. SiO stretching vibrations in the layered silicate shifted to lower wavenumbers with increasing temperature; this indicated the presence of weaker polymer‐layered silicate interactions. The results of this study demonstrate that for the polymer nanocomposites prepared by melting intercalation, more important interfacial interactions existed between the polymer and the surfactant. © 2012 Wiley Periodicals, Inc.
