    摘要： A membrane including a polyarylether having amide functionality. The polyarylether having amide functionality includes units from at least one of structure I or structure II: R1 and R2 are separate groups or are covalently connected to form a cyclic moiety; R1 and R2 are each, independently, hydrogen, C1-20 alkyl, C3-C30 aryl or a substituted C3-30 aryl; R3, R4, R5, R6, R7 and R8 are each, independently, a nitro group, C1-C12 alkyl, C3-C30 aryl or a combination; Y is hydrogen, C1-20 alkyl or C3-C30 aryl; k is from about 0 to about 10; a, b, c, d, e and f are each, independently, 0, 1, 2, 3 or 4; and m and n are each, independently, 0 or 1.

    摘要： A method for the formation of a membrane is described. A collection of substantially spherical particles formed from a selected material is contacted with at least one reactive material. The reactive material is cured or otherwise polymerized by various techniques, so that it forms a matrix that substantially surrounds and contains the particles. A portion of the particle material is then removed, so that the matrix contains a pattern of pores that are permeable to selected substances in solution. In some instances, the matrix is formed by an interfacial reaction between at least two reactive materials. Related filtration membranes are also described.
