ICAR-NISA Natural rosin based high performance conducting ink

Technology Details:

This innovation provides a rapid, single-step process to formulate a versatile, cost-effective, and eco-friendly conducting ink using natural rosin as a conductivity enhancer and binder. Unlike traditional metal-based inks that rely on expensive materials and require complex post-deposition sintering, the rosin-based ink leverages the unique chemical properties of rosin to improve adhesion, cohesion, and dispersion of carbonaceous conductive particles like graphite, graphene, and carbon black. The formulation combines rosin with eco-friendly carbon materials in an optimized ratio to achieve high conductivity and stability, eliminating the reliance on toxic or costly materials such as silver or indium tin oxide (ITO).

Unique features of the solution include its natural and abundant raw material base, environmentally sustainable formulation, and compatibility with a wide range of printing techniques like inkjet, gravure, aerosol jet, flexographic, and screen printing. The ink can be directly applied to flexible and rigid substrates without additional processing, making it suitable for diverse applications in printed electronics, including sensors, circuit boards, RFID tags, and flexible displays. By addressing cost, environmental impact, and performance simultaneously, this innovation positions itself as a transformative solution for the growing market of green and sustainable electronics.
