一般說明

This silver nanopowder consists of metallic silver nanoparticles with a diameter less than 100 nm. These nanosilver particles are coated with polyvinylpyrrolidone (PVP) at a concentration of 0.2% by mass. This coating effectively limits surface oxidation and enhances the dispersion of the powder in various solvents.

Silver nanopowder is extensively utilized in medicinal applications and medical devices. The increased surface area to volume ratio and heightened reactivity of nanosilver make it particularly valuable in modern biomedical applications, particularly in coatings of medical devices.

應用

使用银纳米线配制水基油墨。已对导致更多可洗脱物质的银纳米颗粒进行研究。 对银纳米颗粒 (AgNPs) 的免疫佐剂作用进行了体外 和体内 研究 制造了基于银纳米颗粒的石墨环氧纳米复合材料。 有研究表明,AgNP 可通过增加血小板聚集和促凝血活性促进血栓形成。已制备 AgNP 光致沉积的光纤传感器。 含 Ag 和羟基磷灰石作为纳米添加剂的 PAN 纤维基纳米复合材料已有报道。
