Abstract
Filter media comprising one or more layers comprising nanofibers are generally described. In some embodiments, a filter media comprises a layer comprising nanofibers. The nanofibers may comprise an elastomer, a multiblock copolymer, and/or a multiblock copolymer that is an elastomer.
Claims29
A filter media, comprising:
- a first layer comprising nanofibers, wherein the nanofibers comprise a multiblock copolymer comprising one or more poly(amide) blocks, and wherein the one or more poly(amide) blocks make up greater than or equal to 20 mol % and less than 100 mol % the multiblock copolymer;
- and
- a second layer.
A filter media, comprising:
- a first layer comprising nanofibers, wherein the nanofibers comprise an elastomer, and wherein the nanofibers are at least partially fibrillated;
- and
- a second layer.
A filter media, comprising:
- a first layer comprising nanofibers, wherein the nanofibers comprise an elastomer, and wherein the first layer has an initial water contact angle of greater than or equal to 70°;
- and
- a second layer.
