2014-07-20 (Su) Conductive Paint Experiment

Three plastic screw top jars were chosen because they were useful for mixing and storing the final products. Graphite powder was added to each jar. Three different mediums were selected for testing.

  • Elmer’s Glue-All 
  • Titebond III wood glue 
  • Acrylic paint

 Materials and containers

 Graphite filled jars

Elmer’s Glue-All was added to the first jar and mixed with a clean wooden toothpick. Glue was added until a spreadable consistency was reached. A thin line of glue/graphite was made with the toothpick as a stylus. A wider line was also made before the toothpick was wiped off and all three samples were allowed to dry.

Titebond III was added to the first jar and mixed with a clean wooden toothpick. This glue had a more liquid consistency than Elmer’s Glue-All so less was needed. Graphite powder was added until a spreadable consistency was reached. A thin line of glue/graphite was made with the toothpick as a stylus. A wider line was also made before the toothpick was wiped off and all three samples were allowed to dry.

Acrylic paint was added to the first jar and mixed with a clean wooden toothpick. Glue was added until a spreadable consistency was reached. A thin line of glue/graphite was made with the toothpick as a stylus. A wider line was also made before the toothpick was wiped off and all three samples were allowed to dry.

The nine samples were dried under light air movement. The jars were sealed and labeled. The samples dried for thirty minutes. Ohmmeter probes were fastened together to ensure the readings would be consistent fixing the distance between the probe tips.

To complete the experiment a control sample should be done with commercially available conductive paint. A uniform application method would also be advantageous.

To do:
  • Confirm readings after a longer drying period 
  • Perform control samples 
  • Devise applicator method
