Popis: | In this work, we characterize the capillary performance of copper inverse opals (CIOs) fabricated using template-assisted electrodeposition. A bed of sintered 5 µm-diameter polystyrene spheres is used as a template. The extent of sintering tailors the window diameter between adjacent pores of the CIOs; these windows largely determine the permeability and capillary characteristics of the CIO structures. Capillarity is characterized through rate-of-rise measurements and compared with corresponding changes in permeability determined previously. Trends in these measured values are studied as a function of sintering parameters for the template and resulting porosities of the CIO structures. Findings from this study provide insights into the flow characteristics of copper inverse opal structures, paving the way for designing optimal thermal solutions to electronic cooling applications with microporous metals. |
