March 3, 2025, Shanghai - Gaseous silica, a nano material produced by the high-temperature hydrolysis of chlorosilane in a hydrogen oxygen flame, is performing a stunning "invisibility technique" in the modern industrial field. Gaseous silica, with its nanoscale particle size and excellent dispersibility, can be uniformly dispersed in the material matrix, forming stable suspensions or solutions. In epoxy resin composite materials, coating systems, silicone rubber products, and pharmaceutical applications, fumed silica plays a crucial role due to its unique physical and chemical properties, but it is difficult to be directly observed.


 
In epoxy resin composite materials, gas-phase silica is modified with surface silane coupling agents to form chemical bonds with the resin matrix, significantly improving the material's tensile and tear strength. In the coating system, gas-phase silica constructs a reversible network through hydrogen bonding to achieve thixotropic regulation of the coating. In addition, in silicone rubber products, fumed silica can significantly improve the tensile strength, tear resistance, and wear resistance of rubber. In pharmaceutical applications, fumed silica serves as a drug carrier, enabling slow release and targeted delivery of drugs.
With the aging population and the increasing demand for health, the demand for gas-phase silica in the pharmaceutical market will continue to grow. In the future, the application of fumed silica in the pharmaceutical field will be more extensive, such as for manufacturing targeted drug carriers, intelligent drug release systems, 3D printed biomaterials, etc.
However, the application of fumed silica in the pharmaceutical field also faces some challenges, such as the need to further improve the biocompatibility and safety of materials, and develop more functional fumed silica materials. In the future, it is necessary to strengthen industry university research cooperation, increase research and development investment, and promote greater breakthroughs in the application of gas-phase silica in the pharmaceutical field.
