ABSTRACT:
A dielectric material formed by contacting a low dielectric constant polymer with liquid or supercritical carbon dioxide, under thermodynamic conditions which maintain the carbon dioxide in the liquid or supercritical state, wherein a porous product is formed. Thereupon, thermodynamic conditions are changed to ambient wherein carbon dioxide escapes from the pores and is replaced with air.
