The power law relationship has been used to some extent in order to compare dielectric breakdown strength results between materials of varying thickness. However, especially in case of relatively new materials such as nanocomposites, it can be questioned whether the measured results actually behave accordingly to the power law and to what extent – most importantly, can the power law be used to predict properties of thinner films than those actually measured. This paper addresses the problem in case of biaxially oriented PPsilica nanocomposite films of different thickness, the breakdown results of which are compared and fitted to the power law relationship.
