Abstract
A polymer matrix composite comprising a porous polymeric network; and a plurality of functional particles distributed within the polymeric network structure, and wherein the polymer matrix composite has an air flow resistance at 25° C., as measured by the “Air Flow Resistance Test,” of less than 300 seconds/50 cm3/500 micrometers; and wherein the polymer matrix composite has a density of at least 0.3 g/cm3; and methods for making the same. The polymer matrix composites are useful, for example, as filters.
Claims20
A polymer matrix composite comprising:
- a porous polymeric network structure comprising ultra-high molecular weight polyethylene, ultra-high molecular weight polypropylene, or a combination thereof;
- and
- a plurality of functional particles distributed within the polymeric network structure, each of the functional particles having a surface and one or more functional groups directly attached to the surface or attached to a linker group which is in turn attached to the surface,
- wherein the polymer matrix composite has an air flow resistance at 25° C., as measured by the Air Flow Resistance Test, of less than 300 seconds/50 cm3/500 micrometers.
