  • MICROBALLOON-FACILITATED TUNABLE POROSITY OF ELASTOMERIC SHAPE MEMORY POLYMER COMPOSITES
    Publication number: 20220064481
    Abstract: A product includes a porous three-dimensional printed structure having printed filaments arranged in a geometric pattern. The printed filaments include a material having a plurality of gas-filled microballoons. The printed structure has hierarchical porosity including an inter-filament porosity defined by the arrangement of the printed filaments, and an intra-filament porosity of the material. The intra-filament porosity is defined by the plurality of gas-filled microballoons in the material of the printed filament.
