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.

Provided herein is a method for preparing microcarrier particles, comprising the steps of allowing the dispersed phase liquid flow through a multi-hole plate at a low temperature to form liquid microspheres in a continuous phase, and enabling a synthetic polymer and/or natural biological macromolecules within the liquid microspheres to be subject to a curing reaction at a low temperature to form particles. Further provided herein are the method for preparing an emulsion and an apparatus and process system for preparing microcarrier particles, which can be used for preparing emulsions and microcarrier particles on a large scale.
