FABRICATION OF SILICA/TIO2 NANOTUBES AND THEIR APPLICATION TO ELECTRORHEOLOGICAL FLUID

摘要

PURPOSE: A producing method of silica/titanium dioxide nanotube, and the application of the silica/titanium dioxide nanotube to electrorheological fluid are provided to economically produce the silica/titanium dioxide nanotube. CONSTITUTION: A producing method of silica/titanium dioxide nanotube comprises the following steps: dispersing silica nanotubes inside an ethanol and acetonitrile mixture solution; adding an ammonia solution into the silica nanotube dispersed solution, for applying ammonium positive ions to the surface of the silica nanotubes; inserting a titanium dioxide precursor into the silica nanotube dispersed solution for performing an interface sol-gel reaction on the surface of the silica nanotubes; and dispersing the obtained silica/titanium dioxide nanotube in silicon fluid for obtaining electrorheological fluid.
