Three-dimensional assembly method of ceramic fiber sponge

Ceramic fiber sponge with low density，high specific surface area，high porosity，good thermal stability and good thermal insulation performance is expected to become one of the most promising commercial ceramic materials in the fields of heat insulation，flame retardant，water-oil absorption and energy conversion. This paper summarizes the direct assembly methods such as three-dimensional electrospinning，solution blowing spinning and centrifugal spinning，reviews the research progress in the production of ceramic fiber sponge by direct spinning method，analyses the problems of low production efficiency of ceramic fiber sponge，and proposes the future development directions of ceramic fiber sponge：（1）improve the production efficiency，reduce the production cost，and mass produce ceramic fibre sponge with controllable shape；（2）improve the high-temperature thermal insulation performance and promote the application of ceramic fibre sponge in the field of heat insulation；（3）improve the structural stability and produce ceramic fibre sponge with high elasticity，flexibility，and fatigue resistance；（4）research and develop ceramic fibre sponge materials with special functions such as light and electromagnetism，and expand the application range of ceramic fibre sponge.
