    摘要： The present disclosure relates to nanoporous micro-spherical polyimide aerogels and a method for preparing the same. The use of the method for preparing polyimide aerogels, according to an embodiment of the present disclosure, enables the preparation of the polyimide aerogels through a low-temperature process, and thus can save energy and time when compared with existing preparing methods, can reduce production costs, and can prepare spherical polyimide aerogels, which are micro-sized uniform particles, having excellent chemical stability, thermal insulation characteristics, and absorption-desorption characteristics while having nano-sized pores. The spherical polyimide aerogels can be applied to various fields, such as an insulator, a drug delivery medium, and a catalyst supporter, due to excellent physical properties thereof.
