(456e) Design and Scalable Fabrication of Three-Dimensional Hierarchically Porous Superstructures? for Flexible Self-Powered Electronics, Catalysis, and Water Purification

The recent exploration of advanced materials for the next-generation flexible energy storage devices, electronics, catalysis, and environmental remediation has focused on the unique class of three-dimensional (3D) porous superstructures with fascinating electric, mechanical, and chemical properties. In this talk, I will discuss several innovative schemes for fabricating scalable 3D hierarchical porous foams using rational and low-cost processes, including additive electrodeposition, subtractive electroetching, and electrostatic assembly. The efforts result in first-of-its-kind superstructures made of thin graphite, metals, oxides, and polymer composites with designed features, sizes, morphologies, and tailored properties. These materials underpin high performances in applications, ranging from self-powered strain sensors, portal electromechanical manipulation systems, water oxidation catalysis, to point-of-use water disinfection.
