发明名称 CARBONIZED SHAPED POLYMERIC FOAM EMI SHIELDING ENCLOSURES
摘要 Carbon foam enclosures for at least partially or mostly shielding an at least partially enclosed volume from electromagnetic inference, and a method for using such enclosures, are described. The enclosure may comprise a continuous, non-planar piece of carbon foam. The continuous, non-planar piece of carbon foam may comprise at least two walls an angle greater than zero degrees and define at least a partially enclosed volume. Alternatively, the enclosure may include at least one curved wall and define at least a partially enclosed volume. The carbon foam of the enclosure is electrically conductive. The invention may also include a method for producing a carbon foam electromagnetic interference shielding enclosure. The method may comprise providing a continuous, non-planar carbonizable polymeric foam enclosure, heating the carbonizable polymeric foam enclosure to an first elevated temperature to provide a carbon foam enclosure, and heating the carbon foam enclosure to a maximum elevated temperature to provide carbon foam having an electrical resistivity of less than about 1 ohm-cm.
