Product Overview
Nano silver flakes typically exhibit a thin geometric shape, with a thickness typically at the nanoscale, and a planar size ranging from tens of nanometers to several micrometers. This unique sheet-like structure gives it a large aspect ratio, for example, the aspect ratio of some nanosilver sheets can reach tens or even hundreds. This aspect ratio endows nanosilver sheets with unique advantages in certain applications, such as in conductive coatings, where nanosilver sheets can overlap with each other to form a good conductive network, improving the conductivity of the coating. The surface of nanosilver flakes is usually smooth, and there may be some defects or irregularities at the edges. The arrangement of surface atoms is different from that of internal atoms. Surface atoms have higher activity and chemical unsaturation, which enables the surface of silver nanoparticles to interact strongly with the surrounding environment, such as adsorbing gas molecules and reacting with other chemical substances. The crystal structure of nanosilver flakes is similar to that of bulk silver, generally a face centered cubic structure. However, at the nanoscale, there may be some special phenomena in its crystal structure. For example, due to size effects, the crystal structure of nanosilver sheets may exhibit a certain degree of lattice distortion. This lattice distortion may affect the physical and chemical properties of nanosilver sheets, such as electronic structure, optical properties, etc. The crystal orientation of nanosilver sheets can also affect their properties. Different crystal orientations may lead to different optical and electrical properties of nanosilver sheets. For example, certain nano silver sheets with specific crystal orientations may exhibit stronger surface plasmon resonance effects under specific wavelength light irradiation, thus having unique value in optical applications.
