Continuous Fabrication of Hierarchical and Asymmetric Bijel Microparticles, Fibers, and Membranes by Solvent Transfer‐Induced Phase Separation (STRIPS)

Abstract

Continuous generation of hierarchical and asymmetric bijels based on solvent-transfer-induced phase separation (STRIPS) is demonstrated. In STRIPS, phase separation is induced by solvent extraction from an initially homogeneous ternary mixture, and bicontinuous morphology is stabilized by inter-facial attachment of nano-particles, which are functionalized in situ. STRIPS allows stable bijel formation from a wide variety of liquids and particles.
