Abstract
According to one embodiment, a mixture includes a fluoropolymer monomer having at least one functional group amenable to polymerization, a pore-forming material, and a polymerization initiator. According to another embodiment, a product includes a porous three-dimensional structure comprising a crosslinked fluoropolymer, where at least 20% of a volume measured within an outer periphery of the porous three-dimensional structure corresponds to the pores.
Claims20
A mixture, comprising:
- a perfluoropolyether monomer having at least one functional group amenable to polymerization, wherein an amount of the perfluoropolyether monomer is in a range of greater than 20 weight % to about 95 weight % of the total weight of the mixture,
- wherein the perfluoropolyether monomer is the only monomer in the mixture;
- a pore-forming material;
- a polymerization initiator;
- and
- a polymerization inhibitor.
