Glass immediately comes to mind as having less creep. If you go back to the Faraday, Hertz, Tesla et al days when they were arcing kilovolts across their labs you’ll often see them using glass insulators. Some ceramics and Teflon too.
- dmoy 2y agoMy recollection is that glass has drastically higher dialetric constant than air, but more creep (still very little creep, but more than the ~0 of air). If you're arcing kilvolts, you want that higher dialectric constant, and probably don't care about small amounts of creep. If you're building a supercapacitor, that equation might be different because the voltages can be quite small. I've been out of EE for a long time though, so maybe I'm misremembering things here.
