This study presents the formulation and development of silicon nano-composite based conductive ink for possible screen printing of selected electronic devices. An XRD technique was employed to characterize and the result analysis showed that the particles were nano- sized Silicon nano-composite based conductive inks were formulated and developed from milled silicon nano-particle which served as the dispersed phase or filler materials and dispersed in styrene acrylic and distilled water. A modified screen-printing method was adopted for the deposition of formulated inks on ceramic substrates. Current-voltage characteristics of the printed electronic devices were obtained and employed to determine the nature of interface, behavioural responses upon voltage application, resistivity, effect mass of charge carrier, and barrier height of the con ductive inks. The study revealed that the mass fraction of silicon nano-particle and styrene acrylic in ink formulation E meets the needs of additive manufacturing technology of selected electronic devices.
