Applications:
Silicon dioxide nanoparticles are widely employed as high-efficiency additives and functional fillers across multiple industries. In polymers, rubbers, ceramics, glass, adhesives, and coatings, they enhance thermal stability, mechanical strength, and barrier properties. Their use in paper, fibers, and textiles also improves finish and durability.
In the construction sector, these nanoparticles are blended into concrete, cement, and other building materials as nanofillers to increase compressive strength, reduce shrinkage, and extend service life.
The biomedical field utilizes SiO₂ nanoparticles for drug delivery systems, biosensors, and theranostic platforms, benefiting from their biocompatibility and surface-modification potential. Additionally, they are used in environmental protection applications such as air purification, water treatment, and pollutant absorption systems, contributing to cleaner technologies.
