Abstract
Filtration membrane comprising polymeric nanofibers and/or microfibers attaching dendrimer component presenting reactive sites selective for chemicals to be filtered, and related nanofibers and microfibers, composite materials, compositions, methods and system.
Claims45
A filtration membrane comprising:
- a plurality of fibers comprising nanofibers, microfibers, or a combination thereof, each plurality of fibers having a polymer component and a dendrimer component,
- wherein the polymer component provides a fiber scaffold and the dendrimer component is attached to the polymer component and presents reactive sites on the fiber scaffold, and
- wherein the dendrimer component comprises dendrimers covalently cross-linked to one another to form water-insoluble dendritic particles.
A nanofiber or microfiber comprising:
- a polymeric component providing a fiber scaffold;
- and
- a dendrimer component attached to the polymeric component to present reactive sites on the fiber scaffold,
- wherein the dendrimer component comprises dendrimers covalently cross-linked to one another to form water-insoluble dendritic particles.
