2014-07-23 (W) Conductive Paint Experiment

At the suggestion of +Andrew Hall a batch of conductive glue was mixed from silicone and graphite powder. The goal was to make a flexible, waterproof, and conductive glue. A jar was partially filled with clear silicone then graphite powder was added. The ingredients were mixed with a wooden toothpick identical to the toothpicks used previously in this experiment. The mixture was dark and glittery. A thick line was painted using the toothpick as a stylus.

 Parts: Silicone, graphite powder, and jar

A resistivity test was conducted after the line dried for two hours. The resistance appeared to be ∞Ω so the probes were unfastened to place the tips closer together but no resistance could be measured at any distance. The mixture had an attractive appearance but was not a suitable conductor.
