A Fourier transform Raman study of water sorption by Kevlar-49

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

The Fourier transform (FT) Raman spectrum of poly (p-phenylene terephthalamide) (Kevlar-49) is reported. Additional bands, not observed in the conventional Raman spectrum, have been assigned. The changes to the FT-Raman spectrum of Kevlar due to the presence of water have also been examined. As a consequence of the intensity changes to certain Raman modes in this preliminary study, it is postulated that water molecules form liquid-like clusters between the crystallite regions of Kevlar fibres.
