1. A multimodal coating, the multimodal coating comprising:
a medium;
a structural framework embedded in the medium forming an intumescent coating, the intumescent coating configured to undergo intumescent expansion of an outermost coating of the medium upon heating; and
a metastable material, the metastable material including calcium oxalate, and wherein the metastable material is configured to absorb heat through endothermic reactions as the metastable material undergoes phase transitions.
