ABSTRACT:
A membrane structure is provided. The membrane structure includes a polymer layer having a plurality of pores; and a ceramic layer disposed on the polymer layer. The ceramic layer has a plurality of substantially unconnected pores. Each of the substantially unconnected pores is in fluid communication with at least one of the pores of the polymer layer. A method of manufacturing a membrane structure is provided. The method includes the steps of providing a polymer layer having a plurality of pores; and disposing a ceramic layer on the polymer layer. Disposing a ceramic layer includes depositing a metal layer on the polymer layer; and anodizing the metal layer to convert the metal layer into a porous layer. At least one of the depositing step and the anodizing step is performed as a continuous process. Alternatively, at least one of the depositing and the anodizing step is performed as a batch process.
