Nano-silicon dioxide has a large specific surface area, a large number of surface hydroxyl groups, high reactivity, safety and non-toxicity, low cost, and simple preparation. It has broad application prospects in the fields of textile fibers, plastics and rubber, reaction catalysis, biomedicine, and ceramic materials.


Nanomaterials are defined as materials whose own or constituent particles have one or more dimensions in the nanoscale range (usually 1-100 nm) in three-dimensional space. This inherent property of the composition structure gives it surface (interface) effects, small
