In alkaline condition (pH=13),silver oxide (AgxO) with two valence states was prepared by using strong oxidant.And the product was blended with graphene oxide (GO) to form AgxO/GO composites that were then appiled as functional fillers in styrene butadiene rubber(SBR).Studies shown that the Icorr value of AgxO/GO/SBL was only 2.2×10-7A/cm2,which was lower than that of GO/SBL (4.6×10-7A/cm2) and SBL (1.0×10-5A/cm2),and the value of charge transfer impedance increased,indicating better anticorrosion ability.From the antibacterial experiment,the bacteriostatic efficiency of AgxO/GO/SBR coatings against E.coliattains 87.4%,which was attributed to the high-efficiency bacteriostatic performance of Ag+ and Ag3+ released from AgxO.Therefore,AgxO/GO/SBR was a multifunctional coating with anticorrosion and antibacterial properties.
