| 英文摘要 | The aim of this work is to investigate the interfacial structure of poly(phenylenevinylene)(PPV)/TiO2, nanocomposite by analyzing X-ray absorption spectroscopy at the Ti K edge. The pre-edge regions of X-ray absorption near-edge structure (XANES) spectra displayed distortions of octahedral geometry (TiO6) in the surface of TiO2 nanoparticles, while the post-edge regions of XANES showed PPV could modify the surface of nano-TiO2. From analyzing extended X-ray absorption fine structure spectra of the nanoparticles and comparing them with bulk TiO2, it was found that bond length (Ti-O) and coordination number decrease in nano-TiO2, which is attributed to coordinatively unsaturated TiOx, surface species (x < 6). In PPV/TiO2 nanocomposite, PPV molecule can bond to the surface of TiO2 nanoparticles, leading the interfacial structure reconstructed. (C) 2002 Elsevier Science B.V. All rights reserved. |
