silicon dioxide amorphous nano powders modification:

1. Alcohol, acid modification

Experiments showed that alcohol and acid compounds will react with a large number of -OH of silicon oxide nano powders surface, so organic groups are grafted in the surface of nanoparticles, and the hydrophobic properties of the modified powders got improved, so as to improve the compatibility of the nano powders and organic matter

2. Surfactant modification

1) by physical adsorption surfactant is adsorbed on the surface of nanoparticles;

2) certain groups of surfactant react with -OH of the surface of the particles,which achieve the goal of the surface modification of the particles.

3. The silane coupling agent modification

Experiments show that the coupling agent reduce the interaction between particles, and influence degree of different coupling agent on the modified samples is different.

Application of silicon dioxide amorphous powder

Silicon dioxide amorphous nano powder used as additive for plastics, rubber, ceramics, porcelain, glass, adhesives, fibers, and many other products. It is added to concrete and constructrion composites as strengthening filler. It has also applications in biomedical field such as drug deivery and theranostics. Silicon dioxide is also used in environmental protection products.
