英文摘要The aim of this article is to investigate the effect of interactions between metal ions and polyurethanes(pu) on the properties of polyurethanes. in this report, interaction between metal ions(y(3+), la(3+), ca(2+), cu(2+), and li(+)) and polyurethanes was investigated by ft-ir spectroscopy, theological method and tem technique. compared with the pure pu, obvious variation of carbonyl group vibration can be observed from the ir spectra of pu-ycl(3), pu-cucl(2) and pu-licl composites, which indicated that there were interactions between these metal ions and the polar carbonyl groups of pu. although the ir spectra of pu-cacl(2) systems showed little changes, the difference of theological behavior between pu-cacl(2)-dmf solution system and pure pili solution implied that the aggregation state of pu changed in the presence of ca(2+) ions, which provided the evidence that interactions between metal ions and the molecular chains of pu occurred in the solution, and similar behavior can be observed in pu-ycl(3), pu-cucl(2) and pu-licl solution systems, respectively. tem of pu-lacl(3) results revealed that pu possesses the ability to coordinate with metal ions, resulting in the formation of the ion clusters and phase separation in the pu-metal ion systems. in summary, there are interactions between metal ions and the carbonyl groups of pu in solid state and in dmf solution, which may provide a new way to modify the properties of polyurethanes.
