Silver coated glass fiber has some attractive performances such as antistatic, anti-electromagnetic-radiation, deodorization, antibacterium and radar-reflection. The technology of the electroless silver plating on glass fiber has the advantages of simple fabrication, and uniform coating with strong adhesion, and receives more and more attention in recent years. The preparation methods and applications of elctroless silver plating on glass fiber are introduced, the influence factors of electroless silver plating on glass fiber are discussed in detail. Finally some problems in preparation and application are suggested.
