  • Nanocomposite solution with complex-function and method for preparation thereof
    Patent number: 7763159
    Abstract: A method for preparation of nanocomposite solution, comprises preparing basic silica colloid aqueous solution; providing an electrolysis apparatus by installing a negative electrode containing aluminum and a positive electrode containing silver into the basic silica colloid aqueous solution; and forming nanocomposite by applying voltage to the respective electrodes of the electrolysis apparatus. With this configuration, the present invention provides a method of manufacturing solution dispersed with nanocomposite, further particularly to, a method of manufacturing nanocomposite solution having excellent storability and thermal stability and containing silver having antibacterial function, far infrared radiation function, deodorization function.
    Type: Grant
