Title:
SYSTEMS AND METHODS FOR MAKING POROUS FILMS, FIBERS, SPHERES, AND OTHER ARTICLES
Document Type and Number:
WIPO Patent Application WO/2014/031565
Kind Code:
A3
Abstract:
Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. The polymeric material is then at least partially solidified. The soluble material is then removed such as by solvent washing to thereby produce desired porous articles. Also described are systems for performing the various processes.
