Abstract
A method for coating a poly(arylene sulfide) polymer surface with a semiconductive layer for static charge dissipation and/or induction shielding comprises laminating a poly(arylene sulfide) substrate against a copper foil sheet at a temperature above the melting point of the PAS substrate, wherein the copper foil sheet has been treated with a silane selected from a specific group. When the laminate is cooled and the copper foil peeled away, a poly(arylene sulfide) substrate having a semiconductive surface coating is obtained.
