Abstract
The present application describes a composition and method thereof to make low cost environment friendly and highly safe conducive ink by using micro-sized silver particles, water, edible level thickener, water-based solvent, water-based resin and surfactant. The conductive ink may be written by various kinds of writing devices like gel pen, ball pen etc. on various substrates like paper, plastic, metal, etc. form a conductive trace. As additional features of the present application, the composition comprises erasable conductive ink, which is fast curing and conductive immediately upon application, having multiple applications for educational purpose to help students have a better understanding of how electronic work and even design their own electronics conveniently.
