Porous poly(aryl ether ketone) (PAEK) articles are prepared from PAEK/polyimide
blends by selective chemical decomposition and subsequent removal of the polyimide
phase. Porous PAEK articles exhibit highly interconnected pore structure and a
narrow pore size distribution. The porous PAEK articles of the present invention
can be utilized as a porous media for a broad range of applications, including
membranes for fluid separations, such as microfiltration, ultrafiltration, nanofiltration,
and as a sorption media.
