Abstract
Mesoporous poly (aryl ether ketone) articles are formed from blends of poly (aryl ether ketones) with pore forming additives by melt processing, and can be in the form of a monofilament, disc, film, microcapillary or other complex shapes. The method of formation provides for preparation of poly (aryl ether ketone) articles with high degree of surface area and uniform nanometer pore size. The preferred poly (aryl ether ketone)s are poly (ether ketone) and poly (ether ether ketone). The mesoporous articles formed by the method of the present invention are useful for a broad range of applications, including molecular separations and organic solvent filtration.
Claims11
A method for adsorption or absorption based separation comprising the step of contacting a fluid containing a dissolved substance with a mesoporous poly (aryl ether ketone) material surface modified with functional groups, thereby adsorbing or absorbing at least a portion of the substance onto the mesoporous poly (aryl ether ketone) material.
