摘要： Polymer magnet composites including NdFeB in a polycarbonate (PC) binder matrix are processed using processes including batch mixing and twin screw extrusion. One method includes adding PC to a compartment of a batch mixer and mixing the PC while the compartment is at a temperature greater than a flow temperature of the PC, to form a mixed PC material. The method also includes adding a NdFeB magnetic material to the compartment with the mixed PC material in four batches while the compartment is at the temperature greater than the flow temperature of the PC to form a mixed PC and NdFeB magnetic material, wherein each batch is mixed in the compartment for 1 to 3 minutes before the next batch is added. In addition, a total mixing time is 6 to 12 minutes, and the compartment includes an inert atmosphere. Other embodiments are described and claimed.
