Abstract Silver nanomaterial, one of the most active researeh fields in the metal nanometer materials, has a wide arnge of applications because of its unique heat , light , electricity and ism , catalysis and sensitive features .The prePartion methods of silver nanoparticles are discussed ,including chmeical reduction , photoehmeical reduction ,template , sol-gel method, microemulsion , laser ablation method and so main applications of nano-silver in chmeical reactions , optical field, anti-bacterial field and anti-static materials are shortages in the fabrica -tion process of silver nanomaterial are also outlined. The developing trends of the synthetic technique in the Preparation of the silver nanomaterials are Prospected.
