| 其它 | olydimethylsiloxane (PDMS) exhibits multiphysical responsiveness, enabling versatile forms from coatings to foams that emphasize robustness and functionality. However, the development of ultralight PDMS-based aerogels remains unexplored, particularly for systems demanding concurrent electromagnetic and acoustic wave absorption while withstanding challenges from harsh environment. Herein, we report a green and low-cost dual-template method, exploiting the complementary packing behaviors of fine salt and large sugar for the scalable and shape-customizable fabrication of PDMS-based aerogels. They exhibit ultralight weights ranging from 37.3 to 66.5 mg cm−3, which breaks the density limit of traditional PDMS foams (≈100 mg cm−3). Based on the dielectric |
