Abstract
In one aspect, a material structure is disclosed, which includes a macroscopic porous substrate configured to receive a flow of a medium for passage of at least a portion thereof through the porous substrate. At least one porous coating is disposed on at least a portion of an inner surface of the porous substrate, wherein the porous coating comprises a matrix having a plurality of interconnected passages. The porous substrate and the coating are configured to treat at least one contaminant, if any, present in the flowing medium.
Claims25
A material structure, comprising:
- a macroscopic porous substrate having at least one inlet opening for receiving a flow of a medium and at least one outlet opening through which at least a portion of the received medium can exit the macroscopic porous substrate, said macroscopic porous substrate having at least one channel extending from said at least one inlet opening to said at least one outlet opening, said at least one channel having a cross-sectional diameter in a range of about 50 micrometers to about 1,000 micrometers,
- at least one porous coating disposed on at least a portion of an inner surface of said at least one channel of the macroscopic porous substrate,
- wherein said porous coating comprises a matrix having a plurality of interconnected passages and wherein said porous coating has a thickness in a range of about 1 micrometer to about 200 micrometers, and
- wherein said porous coating facilitates at least one of entrapment and retardation of at least one contaminant, if any, present in said flowing medium.
