    Abstract: The invention relates to a method for preparing silica modified by a silane coupling agent. The method comprises the following steps: preparing a kind of coupling agent sol solution by mixing the solvent, water, catalyst and coupling agent; uniformly dispersing silica into the sol solution by means of ultrasonic dispersion or shear dispersion to achieve a turbid solution with uniform dispersion and ideal particle size; and then stirring the turbid solution at a constant speed to make the coupling agent sol reacting with silica to prepare highly hydrophobic silica modified by the coupling agent through controlling the temperature and reaction time. The coupling agent sol solution is obtained by a sol-gel process and silica is uniformly dispersed in the coupling agent sol solution through combined action of various dynamic means to ensure the sufficient reaction between silica and coupling agent, thus to obtain silica modified by the coupling agent.

  • Patent number: 7718819
    Abstract: A process is provided for preparing organofunctional silanes, inclusive of dimers and oligomers, in which individual silanes possess both free and blocked mercaptan functionality or particular mixtures of the organofunctional silanes possess both free and blocked mercaptan functionality. The organofunctional silanes and silane mixtures are useful, inter alia, as coupling agents for elastomeric compositions, e.g., rubber formulations employed in the manufacture of tires, where they exhibit a desirable balance of low scorch and good performance properties.

  • Publication number: 20100068490
    Abstract: A novel, economical electrical insulation method for the production of ultra-thin insulation layers using a solution coating method. Thin hydrophobic self-assembled bi-functional layers of less than 10 nm thick were deposited by a simple solution method and demonstrated to electrically insulate micro-/nano-devices for in-water detection applications. The insulation layer includes a hydrophobic group which repels water and permits superb insulation properties of the ultra-thin layers. The insulation layer has the additional advantages that it binds to a metal or metal oxide surface and to sensing receptors by covalent bonding using standard silane chemistry.
