A method for producing polysulfone micro-particles for 3D printing disclosed. For example, the method includes creating a mixture of polysulfone by dissolving polysulfone in an organic solvent, creating an aqueous solution of a polymeric stabilizer or a surfactant, adding the mixture of polysulfone to the aqueous solution to create a polysulfone solution, and processing the polysulfone solution to obtain polysulfone micro-particles having a desired particle size, a desired particle size distribution, and a desired shape.

A method for continuously preparing graphene powder directly dispersed in an organic system, including: mixing an aqueous graphene oxide dispersion, an emulsifier and an oil-soluble monomer followed by pH adjustment and dispersing to obtain a pre-emulsified dispersion; subjecting the pre-emulsified dispersion to an emulsion polymerization reaction in the presence of an initiator; introducing a reducing agent to reduce graphene oxide; and subjecting the reaction mixture after emulsion polymerization to spray drying to obtain the graphene powder. Equipment used in the preparation method is also provided herein.

The present invention provides multifunctional particulates that release one or more functional compounds in response to environmental triggers and whose external surface modification imparts secondary functionalities to a selected coating composition. For example, disclosed are hydrophobic particles having a smart release mechanism for anticorrosion compounds that release the anticorrosion compounds upon exposure to the local pH changes induced by corrosion processes. Formulations are disclosed for multifunctional smart particles having antimicrobial effects and protections as well.
