Owing to their unique physicochemical properties endowed by the micro/nano structure,polyimide microspheres attracted many attentions.Polyimide microspheres were fabricated via phase inversion emulsification method.The polyimide microspheres prepared by this way were mono-dispersed.PI with hydrophobic group in the molecular structure could be fabricated into microspheres in the microstructure successfully. Stirring rates and emulsion concentrations influenced polyimide microspheres morphology and particle d...
