A method of manufacturing polyimide particles, including: combining a polyimide solution including a polyimide and an organic solvent with an aqueous solution including water in the presence of an emulsifying surfactant at a shear rate from 1,000 to 3,000 revolutions per minute, from 1,000 to 2,500 revolutions per minute, or from 1,500 to less than 2,500 revolutions per minute to form an emulsion; removing the organic solvent to form an aqueous polymer dispersion including polyimide particles; and recovering the polyimide particles, which have a spherical morphology, and a volume based D10 diameter from 3 to 50 micrometers, preferably from 3 to 45 micrometers and a volume based D90 diameter from 3 to 80 micrometers, from 3 to 75 micrometers, or from 3 to 45 micrometers and a volume based D100 diameter from 3 to 100 micrometers, from 3 to 75 micrometers, or from 10 to 75 micrometers. |
