以羟基封端的聚二甲基硅氧烷（ＰＤＭＳ）低聚物为有机组分，以四乙氧基硅烷（ＴＥＯＳ）为无机原料，用溶胶－凝胶法制备了ＴＥＯＳ－ＰＤＭＳ有机／无机杂交材料。研究了材料的机械性能和动态力学行为。所得材料柔软透明，与纯的溶胶－凝胶玻璃差别很大，拉伸强度０．５～１．０ＭＰａ，极限伸长率可达７％，动态力学曲线显示有机物ＰＤＭＳ均匀分散在ＳｉＯ＿２无机网络中，没有出现相分离。 Hydroxy-terminated polydimethylsiloxane (PDMS) oligomers were used as organic components and TEOS-PDMS organic / inorganic hybrids were prepared by sol-gel method using tetraethoxysilane (TEOS) material. The mechanical properties and dynamic mechanical behavior of the material were studied. The obtained material is soft and transparent, which is quite different from the pure sol-gel glass. The tensile strength is 0.5-1.0 MPa and the ultimate elongation is up to 7%. The dynamic mechanical curve shows that PDMS is uniformly dispersed in the inorganic network of SiO 2 , There is no phase separation.
