High dielectric strength insulator

[chenhon5]

Hi,

Does anyone know which insulator will have very high dielectric strength at room temperature?

The dielectric strength is the electric filed strength of a material can resist before it breakdown.

Have a look at Polysulfide sealants.

Or run your experiment under oil (heated first to remove water)

Hi, thank you very much for your reply. i am looking for some material can be deposited using ebeam evaporation or atomic layer deposition, since very thin layer (~30 nm) is needed.
