Abstract

This disclosure relates to dielectric chaff materials or fibers which are small in character for packing and expandable on release to produce clouds of great cross section. Polymer materials are treated chemically and/or irradiated with nuclear or electronic radiation which partially decomposes the polymer. Upon release, the polymer is heated to create gas bubbles from within which expand the dielectric fibers to change the density and shape of the dielectric.
