(10,11) However, the high surface-to-volume ratio of the metallic nanoparticles in the ink material is susceptible to rapid oxidation. ![]() (3,4) IJP has been successfully demonstrated in devices such as printed sensors, (5−7) antennas, (8,9) interconnects, (3,4) and displays. Specifically, additive manufacturing such as IJP is promising to greatly lower production costs because of its superior material utilization efficiency by direct patterning and its scalability. Therefore, this study paves a new pathway toward efficient growth of high-quality graphene on Cu ink for applications in flexible electronics and Internet of Things (IoT). The morphology of Cu ink after the PECVD process and the dependence of the graphene quality on the H 2/CH 4 ratio may be attributed to the difference in the corresponding electron temperature. We investigate the PECVD growth conditions for optimizing the graphene quality on Cu ink and find that the defect characteristics of graphene are sensitive to the H 2/CH 4 ratio at higher total gas pressure during the growth. In this work, we demonstrate the direct growth of graphene on Cu ink deposited on polyimide (PI) by means of plasma-enhanced chemical vapor deposition (PECVD), which provides simultaneous reduction, sintering, and passivation of the Cu ink and further reduces its resistivity. Highly customized and free-formed products in flexible hybrid electronics (FHE) require direct pattern creation such as inkjet printing (IJP) to accelerate product development.
