Abstract: Flake silver powder has attracted tremendous interesting due to its specially electrical and optical properties. Chemical reduction method with the advantages of reaction conditions easily controlled and mass production is widely used to prepare flake silver particles. In order to more easily prepare flake silver particles, the generation mechanism of flake silver particles is studied by analyzing the impacts of reaction conditions, such as pH value, kinds of silver seeds, kind of surfactant and concentration of raw material. The results show that flake silver particles can be prepared through controlling reaction conditions. Some problems existing in the preparation of flake silver particles are put forward, and future research directions are also proposed.

Abstract: Antenna of RFID tag is used to spread frequency signals and build wireless connection between the tag and reader. High cost, low production speed and environment pollution exist in the traditional methods of manufacturing antenna. In order to overcome the disadvantages above, the method of printing antenna with conductive ink is being widely researched. So, conductive ink gets more and more attention. In order to study the performances of conductive ink better, conduction mechanism of conductive ink are mainly discussed. The requirements of conductive ink to print antenna are described. The present status of conductive ink in printing antenna is introduced, and research directions in future are also predicted.
