Abstract

A series of polyimide films, whose repeating units had different contents of fluorine atoms in the structure, was subjected to swelling in supercritical carbon dioxide. The greatest increase in the free volume was 257 % of the initial value. This led to the formation of foams and reduction of the dielectric constant even below 1.5.
