Synthesis of Some New Functionalized Octasilsesquioxane Hybrid Nanoclusters.III.Potential of the Octameric Clusters as Hydraulic Lubricating Fluids

摘要

The reaction of suitable organic compounds such as omega-halo-1-alkenes,allyltrichlorosilane or 2-methyl-3-butyn-2-ol in combination with a well-defined inorganic silsesquioxane,H_8Si_8O_(12)A cores,leads to covalently bound organic-inorganic hybrid materials in high yields.The hydraulic fluid properties of these viscous hybrid materials were evaluated and compared with those of some commercially available hydraulic fluids:Mobil EAL 224H,Super-V(AP)and Puroil SHO.The results showed that most silsesquioxane semi-liquids possess hydraulic fluid properties comparable to those of the 3 commercial lubricants.
