FILM MATERIAL COMPRISING METAL SPIKES AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a film material comprising metal spikes (8) and surfaces (2 and 3) located opposite one another, whereby the film material (1) has passages (4) extending from one surface (2) to the opposite surface (3). These passages (4) are filled with needlepoint-shaped conical pins (5) or plated holes (6) comprised of electrically conductive material, whereas the surrounding film material is, in a preferred embodiment of the invention, made of an insulating synthetic material (7). Another embodiment of the invention provides that in lieu of the insulating synthetic material (7), the needlepoint-shaped pins are surrounded by air or by another gaseous medium. The invention also relates to a method for producing a film material (1) of the aforementioned type, and to uses for the film material (1).
