| Abstract Scope |
Macropore-infused nanocomposite thermosets (MINETs) offer a unique construct to tune material 3D architectures through high-shear mixing followed by curing of (1) a structural resin, (2) a working fluid, and (3) micro/nanoparticles as enabled by (4) a compatiblilizing surfactant. MINETs have tunable composition, pore sizes (0.1–10 μm), and microstructure with low shrinkage and are compatible with a wide range of manufacturing approaches, including molding, additive manufacturing, and incorporation into carbon fiber composites. Notably, selection of, in particular, the particle and working fluid can enable different functionalities, provided that appropriate resin and surfactant can be identified. Here, we will highlight three such applications: (i) battery electrode or separator architectures using ionic liquid working fluids, (ii) structural energetics using fuel-oxidizer particles and working fluids, and (iii) flame-resistant composites using silicone working fluids. |
