nanosilicates

Nanosilicates are a class of materials derived from silicates that exist at the nanoscale. This means at least one of their dimensions is between 1 and 100 nanometers. They are typically composed of silicon and oxygen atoms arranged in tetrahedral structures, which can then polymerize into various forms. Common examples include layered silicates like montmorillonite and kaolinite when exfoliated or fragmented to nanoscale dimensions. Other nanosilicates can be spherical or fibrous. Their unique properties arise from their extremely high surface area to volume ratio and quantum mechanical effects. These properties make them attractive for a wide range of applications. Nanosilicates are often used as reinforcing fillers in polymers to improve mechanical strength, thermal stability, and barrier properties. They find use in nanocomposites for automotive parts, packaging, and construction materials. Their layered structure also makes them useful as catalysts or catalyst supports due to the available active sites. Furthermore, nanosilicates are explored for their potential in drug delivery systems, environmental remediation, and as components in advanced coatings. The synthesis and processing of nanosilicates are active areas of research, aiming to control their size, shape, and surface chemistry to optimize performance for specific applications.
