[Study on structure and spectral properties of carbon nanotubes doped silica gel glass composites]

Carbon nanotubes (CNTs) were successfully introduced into silica gel glass matrix by physically doped sol-gel technique. The characterization of structure and spectra of the CNTs doped composites were carried out by X-ray diffraction, transmission electronic microscope, UV-Vis spectra, IR spectra and Raman spectra. The results show that CNTs are homogeneously dispersed in the silica gel glass matrix and the sol-gel processing does not appear to affect the intrinsic structure of CNTs. The introduction of CNTs doesn't make any noteworthy changes in the UV-Vis and IR spectra of silica gel glass matrix.
