This book highlights the relationship between electrical and mechanical hybridization of graphene nanoplatelet, silver flake, and zinc conductive ink for flexible nanoelectronics. It focuses on optimizing filler loading, curing temperature, and duration to enhance adhesion, conductivity, and mechanical strength. It discusses hybrid ink formulations prepared and tested through resistance and mechanical analyses, including peel, shear, and bending tests. Microstructural evaluations using SEM and EDX confirm uniform dispersion and strong interfacial bonding. Optimized hybrid ink cured at 250 °C for five hours presents low resistivity, excellent adhesion, and high durability under stress. The findings provide valuable insight into curing–adhesion relationships and suggest further exploration of additives to improve high-temperature performance.
