Tóm tắt

Aerogels with porous structures offer an attractive approach to modulating electromagnetic parameters and enhancing electromagnetic wave (EMW) absorption performance. However, conventional aerogels are limited by their single-scale pore size and fixed orientation, which constrain their EMW absorption capabilities. This study introduces aerogels with dual-scale pores and dual-network structure constructed via constant-temperature freezing and secondary-infusion freezing method. Multiscale aerogels with both micrometer- and submillimeter-scale pores are constructed when the Ti
