| titleOfInvention | Method for preparing silicon dioxide with three-dimensional ball chain structure |
| abstract | The invention relates to a method for preparing silicon dioxide with a three-dimensional ball chain structure. The method comprises the following steps: mixing absolute ethyl alcohol and distilled water, adding a surfactant CTAB, dissolving, sequentially adding Tetraethoxysilane (TEOS) and ammonia water under stirring, and finally dropwise adding gamma-methacryloxypropyltrimethoxysilane (KH570) to obtain a white suspension; reacting the white suspension at 25-50 ℃ for 1-6h, separating, washing and drying the product, and roasting at 450-700 ℃ for 5-8 h to obtain the final product, namely the three-dimensional spherical chain silicon dioxide. The silicon dioxide material synthesized by the invention has a three-dimensional framework structure, can effectively improve or solve the problems in the prior art, and the size of the sphere is controllable within a certain range. |
