A lab radio frequency (RF) magnetron sputter coating system was used to deposit the nanoscale copper (Cu) films onto the surface of polyester plain fabric at room temperature. In this study,the polyester fabrics were treated under different duration with low temperature plasma.The effect of oxygen plasma pretreatment on surface morphologies,antistatic properties,mechanical properties of the copper-coated polyester fabrics is investigated. The surface morphology of
modified polyester fabrics was characterized by atomic force microscopy (AFM).The AFM observations revealled the obvious corrasion was formed on the fiber surface,the sputtered copper particles were hard to cluster and uniformly distributed on the fiber surface with longer duration of plasma treatment.The antistatic properties of the copper-coated polyester fabrics was greatly improved after the oxygen plasma treatment.The hydrophobic behavior of the coated samples was also significantly improved .
