Static electricity generation. Optimum materials?

[taylaron]

Hello. I'm interested intaking a cloud formed of activated carbon particles and particulates of some other substance to produce static electricity similar to that formed in a cumulonimbus cloud. The means of containing this experiment is another matter. I understand that when "opposite materials" as some call them are rubbed together, static electricity is best produced.

I want to use particulates of activated carbon, but I don't know what element would be best to produce static electricity when rubbed against carbon.

Could someone explain the material requirements to create optimal static friction? Thanks.

Regards,
-Tay

Google the term http://www.siliconfareast.com/tribo_series.htm" . Carbon falls somewhere in there, but is not featured on that page. You will probably have to google extensively the term triboelectric and carbon or graphite.
