Design of Interparticle Photo-cross-linkable Pickering Emulsions and Their Application toward Structuring Porous Ceramic Bodies

Our recent study on the design of interparticle photo-cross-linkable Pickering emulsion were briefly reviewed. The emulsion can be designed by dispersing ceramic particles in continuous phase containing limited amounts of monomers, adding dispersing phase, and conducting vigorous mixing. Photocurable Pickering emulsion was successfully prepared when functionalized polyethyleneimine was used as reactive polymer dispersant. Owing to the high flowability and photo-curability, the designed Pickering emulsion can be applied to various structuring process such as photo-molding, green machining, and stereolithographic 3D printing. Further, the 3D structured ceramic porous green bodies were debindable and sinterable through rapid heating profiles without occurring structural collapse.
