Problems solved by technology

[0003] The sol-gel process of the material can be traced back to the discovery of the French chemist J.Ebelman in 1864, but in order to avoid dry cracking, the aging and drying process takes as long as one year, making this method difficult to be widely used

Abstract

The invention discloses a silicon dioxide hybridization material and the manufacture method. It is made from the following steps: omega-bittern sulphonyl full florin acyl peroxide taking reaction with poly diphenyl dimethoxy silicane, hydrolyzing, solgelizing, acidifying. The material has strong acidity, large surface area, high thermal stability, and is easy to be compounded.

Description

Technical field: [0001] The invention relates to a functional hybrid material and a preparation method thereof, in particular to a fluorine-containing silicon dioxide hybrid material and a preparation method thereof. Background technique: [0002] Organic / inorganic hybrid materials combine the excellent characteristics of organic and inorganic materials, and have good mechanical properties, high temperature resistance and good flexibility. In addition, hybrid materials can control the structure of substances in a small range (molecular level), so that the two components can form nanocomposites, which have the characteristics of nanomaterials. Therefore, hybrid materials have broad application prospects in many fields such as mechanics, optics, electronics, separation, catalysis, chemistry, and biology, and have become a new focus and growth point of functional materials research. [0003] The sol-gel process of the material can be traced back to the discovery of the French ...
