silicon tetraethyl
1.With tetraethyl ortho-silicate (TEOS) as main material and through the polymerization-sol process, silicon sol is obtained and is compounded with styrene-acrylic latex to give complex binder, then the silicon sol and styrene-acrylic complex road-mark coatings.
2.Copper substituted hexagonal mesoporous silica(Cu-HMS) was synthesized using tetraethyl silicate(TEOS) as silicon source, CuCl_2, CuAc_2 or Cu(NH_3)~+_4 as copper source and dodecylamine(DDA) as templating agent.
3.Mesoporous composite material of (Bi,B)/SBA - 3 (a material named by the uiversity of Santa Barbara, SB A) was synthesized by using cetyltrimethylammonium bromide(CTAB)as template and tetraethyl orthosilicate(TEOS)as silicon source with the addition of other chemicals such as BiCl3 and H3 BO3. Examination results indicate that the material prepared has a periodic hexagonal structure by X-ray diffraction and high-resolution transmission electron microscopy.
