Ferroelectrets are unusual composites, consisting of a closed-cell polymer-filler foam structure. Ferroelectrets behave like ferroelectric materials during and after internally charging the voids of the cellular structure. In order to optimize the el

The protonation and deprotonation behaviour and the assignment of pK a values of hypericin are reviewed and discussed. Three experiments (electrospray MS, 1H NMR, acid–base indicator equilibria) provided additional evidences for the assignment of p

Ferroelectrets are closed-cell polymer foams that behave like ferroelectric materials during and after internally charging the voids of the cellular structure. In order to optimize the electromechanical properties of ferroelectrets, the voids within

Cellular space-charge polymer electrets can be internally charged by silent or partial discharges ("microstorms") within the voids of the polymer foam. The resulting material, which carries positive and negative charges on the internal void surfaces
