Porous mullite fiber-based ceramics inspired by biomimetic natural pine wood

Preparation of Fibrous Three-Dimensional Porous Materials and Their Research Progress in the Field of Stealth Protection

“…Due to the high strength and stiffness characteristics of microfibers, their assembly into three-dimensional porous materials exhibits limited flexibility, pronounced brittleness, and high strength but poor resilience. Most scholars commonly refer to them as porous ceramic materials [ 25 , 26 , 27 , 28 ]. Simultaneously, because most of their skeletons and pores are at the micrometer scale, both the thermal conduction and convection effects are relatively high, resulting in a relatively high thermal conductivity.…”

“…Due to the high density of microfibers, using a low-density liquid as a dispersant during material formation can lead to fiber sedimentation. Researchers often use substances like starch [ 27 , 29 ] and protein [ 30 ] as low-temperature binders and dispersants to prepare microfibrous three-dimensional porous materials. These substances can rapidly solidify the fiber suspension under certain temperature or catalyst conditions.…”

“…However, after 2020, basic research on fiber types and binder selection has basically reached saturation. Scholars are committed to changing the structure and performance of the fibers themselves [25,26,48] or preparing functionalized biomimetic microfiber porous materials [27,47], and the research direction tends to be consistent with nanofibrous porous materials. mance to construct microfibrous three-dimensional porous materials [34][35][36][37][38][39][40][41][42][43][44][45][46][47].…”
