Composite structure and method of making |
摘要 |
A composite structure, particularly a filter structure, is provided comprising a support having a surface and a porous membrane formed integrally to the surface of the support. The support preferably includes means for directing a fluid away from the surface of the support. The support surface is at least slightly soluble in a solvent. The porous membrane comprises a resin soluble in the solvent and precipitated while the casting solution is in contact with a porous substrate and the surface of the support. The membrane is formed and integrally secured to the surface of the support contemporaneously.
