Abstract
The disclosure describes an article for removing undesired chemical ions or compounds from gas and fluid streams when the stream comes into contact with the article. The article is a porous polymeric matrix having a sorption particle within the porous polymeric matrix structure, the sorption particle is capable of removing the undesired chemical ion or compound.
Claims22
An article comprising a bicontinuous structure of polyvinyl chloride or chlorinated polyvinyl chloride and a polyethylene oxide polymer, the polyethylene oxide polymer having an average molecular weight less than 100,000, wherein the bicontinuous structure comprises a nominal channel size of polyethylene oxide polymer between 100 microns and 1 nm, the article further comprising a plurality of sorption particles, the sorption particles are distributed in the polyethylene oxide polymer and the nominal sorption particle size of the plurality of sorption particles is selected to be greater than the nominal channel size, less than the nominal channel size, or the sorption particles are selected so the nominal sorption particle size is selected to be greater and less than the nominal channel size.
An article comprising a bicontinuous structure of polyvinyl chloride or chlorinated polyvinyl chloride, wherein the bicontinuous structure comprises a nominal channel size between 100 microns and 1 nm, the article further comprises a plurality of sorption particles, the sorption particle is selected from ion exchange, chemisorption, physisorption, chelation, catalysis, or a combination thereof, wherein the nominal sorption particle size of the plurality of sorption particles is selected to be greater than the nominal channel size.
