Abstract
In some variations, a polymer-based microlattice structure includes a plurality of intersecting micro-truss structural elements each comprising a thermoset first polymer, and a continuous coating layer (with a second polymer) that substantially encapsulates each of the micro-truss structural elements, wherein the second polymer in the continuous coating layer bonds the thermoset first polymer to a substrate. The micro-truss structural elements preferably are architecturally ordered and the coating layer is uniformly distributed within the microlattice structure. The polymer coating layer may be present over the entire microlattice surface area, thereby increasing bond area to improve toughness. The microlattice structure may also have higher glass-transition temperature and chemical resistance, compared to a microlattice structure without the coating layer. Methods of forming a polymer-based microlattice structure are also disclosed.
