Hi
I have a project where I am trying to make a coating or paint that will give off heat when an electrical current is passed through it. I got graphite powder and made it into a paste and allowed it to dry on a substrate. The problem is that it is highly resistive (a small section has a resistance of thousands of ohms) so little or no current is flowing though it unless I pass thousands of volts through it (not practical). The other problem is that this graphite coating does not seem to be stable under heat.
Does anyone have any suggestions as to what material/s I can use to form a coating that will have low electrical resistivity, will not degrade at higher temperatures (~60 degrees Celsius) and preferably non-toxic?
Thank you
