Abstract
Polymer composite materials are disclosed containing one or more chemical scavengers. The polymer composites are porous and are configured to be contacted with a liquid for removing trace amounts of metals, proteins, polypeptides, polyphenols, other organic compounds, and the like. In order to produce the porous composite polymer product, one or more chemical scavengers are combined with thermoplastic polymer particles and sintered into a shape. The polymer particles act as a binder trapping or encasing the one or more chemical scavengers in the porous structure.
Claims14
A polymer composite comprising:
- a porous substrate comprising a binder, the binder comprising thermoplastic polymer particles, the thermoplastic polymer particles being sintered together to form a porous structure;
- and
- at least one chemical scavenger contained within the porous structure such that the chemical scavenger is exposed to fluids contacting the porous substrate, the chemical scavenger comprising:
- wherein X+ is a counterion and n is from about 2 to 25,000.
