Abstract
A process for endowing a polymeric article with a surface layer of an ion-conducting polymer to yield electrical surface resistivity sufficiently low for electrostatic discharge applications is provided. The polymeric article contains one or more immobilized, polymeric components having amine functional groups. The presence of the ion-conducting polymer in the surface layer lowers the surface electrical resistivity into the range suitable for electrostatic discharge applications, between about 1×10and about 1×10Ω/□. Plastic electrostatic dissipation materials produced by the inventive process may find use in the optical, electronics, automotive, entertainment, sporting goods, and medical sectors.
