Conductive films
A method of making an electrically-conductive film is provided. The method includes providing a release layer, optionally having a topologically structured surface, and depositing at least one electrically-conductive layer on the release layer whereby the at least one electrically-conductive layer has an outer surface that substantially replicates the topologically structured surface. The electrically-conductive layer can be peeled away from the release layer to obtain the electrically-conductive film. Such electrically-conductive films can be useful in lightning strike applications.
