Multifunctional Hybrid Carbon Foams: Integrating Processing and Performance

Abstract

Finite element models based on X-ray tomography of the carbon foam morphology are developed to characterize response of multifunctional carbon foams. These models incorporate ligament anisotropy as well as coating layers and provide comprehensive information for adapting processing and performance parameters. Illustrations at multiple scales are presented to explore the range of properties in coupled-field environments that are crucial for the emerging multifunctional devices. The results highlight the importance of anisotropy and the impact of common processing defects in tailoring properties. Specifically, coating coverage and quality interfaces are critical in delivering the desired thermoelectrical response.
