일반 설명

The refractive index of silica nanoparticles is similar to polymeric coatings, so it finds several applications in the preparations of nanocomposites. Properties suh as, thermal resistance, electrical and mechanical are enhanced. Silica nanoparticles find uses in various fields of catalysts, pigment stabilization, electronics and sensors.

애플리케이션

Silica nanoparticles have been used :
  • To study the nonlinear optical properties of SiO2 nanocomposites in weak optical fields.
  • As a nanoadditive in nanocomposite calcium alginate fibers.
  • As dispersant in liquid polymethylsiloxane to exihibit unique optical non linearity in low intensity visible radiation fields.
