Mercaptopropyltrimethoxysilane (MPTS) was used to form self- assembly monolayers (SAMs) on glass substrates by solution extraction, which was checked with XPS and AES. These prepared glass slides were used as substrates for electroless Ag plating. XPS study showed that Ag colloids formed in the solution were successfully and firmly anchored on SAMs through Ag-S bonds. By the Ag-Ag interaction, Ag was then deposited to produce a silver-coated glass. SEM and XRD analysis illustrated that the Ag film on the SAMs-modified glass was superior in durability over that of the Ag film on the conventionally modified glass and the crystallinity of Ag film on the SAMs-modified glass was identical to that of the Ag film on the conventionally modified glass and pure Ag.
