摘要：

Two series of inorganic/organic hybrid gels were prepared by the sol-gel reaction of triethoxysilyl-terminated poly(tetramethylene oxide) and tetraethoxysilane. The structure of hybrid gels was observed by small-angle X-ray scattering, and the scattered profiles were analysed by assuming a priori the density correlation functions. The results suggest that the hybrid gel is composed of organic-rich, inorganic-rich and organic/inorganic mixed regions. The size and structure of respective regions were discussed in terms of the correlation lengths evaluated from the scattering profiles.
