Abstract
A compact, highly expandable sorbent made from polymeric materials is contemplated. The resulting sorbent can absorb more than 20 times its original volume owing to an internal foam-like structure having micron-level voids bisected by internal struts which themselves have nano-level pores. Further, this sorbent can be compressed and reused multiple times, thereby making it an ideal substance to facilitate separation of disparate fluids, such as oils floating on or within an aqueous solution.
