This cover by Eric Schmid, David Salem and colleagues shows an SEM of a microvascular epoxy produced by sacrificial removal of PLA fibers. In this example, the microchannel volume fraction is 0.6, and the (~18 μm diameter) channels are primarily oriented longitudinally, with fewer microchannels in the transverse direction. Tensile, flexure, and compression properties were characterized and modeled over a wide range of microchannel fractions and different microchannel orientations, demonstrating the ability to engineer the properties of these materials for structural thermal insulation applications, and for applications requiring liquid transport through the polymer for thermal management, self‐healing and various biomimetic functions.
