What is the easiest way to make plastic conduct electricity? And how to achieve it?

I have read about many methods, but they are just too complicated to be considered as 'DIY". I know it can be done at home, but I dunno how. Plastic after operation should be at least a bit conductive AND transparent.

Polyurethane resin might be a solution. But what should I add to it to became conductive? Preferably something that won't harm a screen.

Of corz I don't expect a miracle. It has to be conductive enough to trigger capacitive touch-screen while holding in hand. (So not much I guess)

You won't get all your wishes, particularly transparent. The simplest and cheapest method probably involves mixing a conductive metal powder with a melted plastic .

What's your application?

I have just read about method involving coating plastic with thin layer of tin oxide. What do you think about it. Would it be easy to accomplish?

Cover it with aluminum foil, or get it chromed.

I did it accidentally some years ago. I had a transformer with a output of 15,000 volts. I used a short piece of CPVC pipe to hold the wires to make a Jacob's ladder. It was working for a few minutes when the arc quit. At first I thought something happened to the transformer. Then I noticed a wisp of smoke coming from the pipe as a tiny whisker of a black line grew from one conductor to the other. The voltage was so high that it started to force current through the plastic. As it did so, it burned and carbonized the path through the pipe. This allowed enough current to flow through the plastic till it kill the arc through the air.

Sandwich thin conductive wires between layers of transparent plastic and glue.

Simple, conductive and transparent?

I'm afraid that all the DIY methods I can think of involve mixing opaque substances (carbon, metal powders) into molten thermoplastic.


The conductive layers in liquid crystal displays are all I can think of, but they must be huge resistance and only designed for microamps of current.
