The paper aims to improve the interface properties of the stainless steel mesh as a resistance welded glass fiber reinforced polyetherimide (GF/PEI) laminate implant by reducing the combination of oxidized ocimene (RGO) and the stainless steel mesh. The welding strengths of different welding times were compared under the same welding process. The improved Hummers synthesis of graphene oxide (GO) and hydrazine hydrate reduced GO were characterized with scanning electron microscopy, infrared spectroscopy and Raman spectroscopy. The stainless steel mesh wrapped with different times of RGO was tested and analyzed with scanning electron microscope and dynamic contact angle. The electric resistance welding test was carried out on the stainless steel mesh wrapped with different times of RGO, the welding strength and failure form were analyzed. Under different welding times, it was determined that the highest single lap shear strength was 26.6 MPa when it was about 120 s. The stainless steel mesh with a different number of RGO coatings on the surface caused the dynamic contact angle to increase from 89.8° to 127.7° due to the hydrophobicity of RGO. Under the optimized welding time, the resistance welding strength of the implant was up to 41 MPa with a stainless steel mesh wrapped with RGO 5 times. At the same time, the addition of RGO changed the resistance welding failure form from the initial stainless steel mesh direct peel failure to the simultaneous tearing failure of the stainless steel mesh and the laminate. The RGO-wrapped stainless steel mesh effectively increases the interfacial compatibility of the pure stainless steel mesh as the implant and the PEI resin, and significantly improves the strength of the resistance welded joint.
