Abstract:

We describe a simple method to prepare a novel kind of water-dispersed polyimide. The resulting polymer particles exhibit a good dispersibility in water, and can form flat films after thermal imidization. The morphologies of particles vary with the chemical structures of polymers, while the temperature plays a lesser role. The spray method is proved to be a promising technique to fabricate polyimide micro- and nano-spheres.
