Title: METHODS OF EXFOLIATING AND DISPERSING A GRAPHITIC MATERIAL INTO POLYMER MATRICES USING SUPERCRITICAL FLUIDS
Abstract:
Embodiments described herein relate generally to systems and methods for manufacturing a master batch with a graphitic material dispersed in a polymer matrix. In some embodiments, a method for manufacturing the master batch can include combining the graphitic material with a polymer, adding a supercritical fluid to the mixture, and depressurizing the supercritical fluid to remove the supercritical fluid. In some embodiments, the method includes mixing the graphitic material and the polymer for a first time period to form a first mixture and transferring the supercritical fluid to the first mixture to form a second mixture. In some embodiments, the method includes mixing the second mixture for a second time period and depressurizing the second mixture to allow the supercritical fluid to transition to a gas phase.
