Abstract

Polyimides have been widely used as high-performance polymers, but controlling their morphology is still challenging. This study focuses on fabricating spherical polyimide particles by the precipitation polymerization of diamine and tetracarboxylic dianhydride monomers. Polyimide particles were prepared by changing the concentration and structure of the monomers in the presence of a dispersant, and the effect of these conditions on the size and distribution of the particles are discussed. The effect of crosslinking by a triamine monomer is also described.
