In this study, we conveniently obtained Ag(0)–polymer nanocomposites by reacting AgNO3 with commercial poly(vinyl acetate) (PVAc) in the absence of a special reducing agent. The formation of Ag(0) metal was detected after formic acid (HCOOH) was ad

A metal chelate polymer (MCP) of PVAc-AgNO3 was prepared by adding AgNO3 salts into the PVAc matrix and was coated on to PET substrate to form PVAc-AgNO3/PET films. These films were then treated with NaBH4 aqueous solution to become the reduced metal
