We present our preliminary work on the fabrication of polyimide hollow sphere by reprecipitation Through fine-tuning the PAA concentration, many intriguing shapes, including deflated capsules, bowl-shaped and dimple-like hollow spheres can be obtained Adding salt to the PAA solution helps the formation of PI hollow spheres with complete shells The morphologies can be fixed through imidization, thus obtaining a controllable and reproducible method to prepare high-performance polyimide hollow spheres with various morphologies
