Quantitative evaluation of delamination of graphite by wet
2015-1-1 The graphite delamination process in NMP was optimized by varying delamination tool, delamination media size and stirrer rotation speed. Processing of graphite in NMP using a stirred media mill under optimized process conditions (100 μm ZrO 2 beads, stirrer tip speed: 3.4 m/s) yields a FLG suspension which is nearly free of graphitic impurities.
