Silicon oxide nano powders (SiO2,20NM,99.8%,Amorphous) Silicon oxide nano powders as the amorphous white powder, is a kind of non-toxic, tasteless, no pollution non-metallic materials. silicon oxide 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.
