An electrochemical method to rapidly assess the environmental risk of silver release from nanowire transparent conductive films

摘要: Abstract Silver nanowires (AgNW) are new nanomaterials designed to be incorporated into transparent conductive films in electronics, microelectrodes, heated surfaces and others. Although these films, the AgNW generally protected by a coating material, risk for release of silver at all stages nanoproduct life cycle does exist due corrodibility metal. Since ionic nanoparticulate Ag represent toxicological large number living cells, there is need quantifying potential from product components. We developed an electrochemical method evaluate possible corrosion activity (TCFs) concomitant Ag+ release. A polysiloxane polymer was used as protective TCFs. consistent correlation observed between degree coatings' characteristics, particular thicknesses. major advantage approach, compared classical aging studies, short experimentation time: 20 min sufficient diagnostic result. The accelerated test. It environmentally sound methodology with use very low electric power no harmful reagents. particularly attractive application could field environmental assessment metals portable electronics biosensors.
