| Abstract Scope |
Architected materials can be used to elicit and direct fluid flow with the ability to control multiphase interfaces [1]. In lattices with sub-mm unit cells, the distribution of a liquid is dominated by surface tension effects. Thus, microarchitected porous media can be designed and manufactured to leverage capillary flow and gas-liquid interfaces in three dimensions. Combining stereolithography with chemical and thermal post-treatment can produce complex microarchitectures with multiple materials, polymers, carbon, and catalytic metals. We discuss design considerations for cellular fluidics devices and illustrate examples of applications, such as fabrication of novel electrochemical devices, CO2 absorbers, electrospray ionization, and structured composite materials [2]. *This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
