It may be ceramic, paper, polymer, oil, etc. In order to charge the capacitor, it has to be connected across a voltage source and the charging current will continuously flow to the capacitor till it is fully charged. Once it is fully charged it by itself becomes a voltage source.
In general use, we usually reserve the working voltage of a capacitor to be twice that of an actual operating voltage.
