Abstract: A kind of PET-Graphene (RGO) conductive material is prepared by treating PET nonwoven with plasma at atmosphere temperature and pressure to introduce amino groups to the surface of the PET nonwoven and then graft graphene to PET. The effects of plasma treatment time on the amino-group concentration and conductivity of the PET-RGO material are investigated. The optimum conductivity condition is 120 s at room temperature under atmospheric pressure. Results show that the grafting modified PET-RGO composite material has excellent conductivity.
