30/12/2003 However, since the hardness of the polymeric grinding media is low, only organic nanoparticles which are easy to be distributed or dissembled are suitable for the grinding through the polymeric grinding media. In addition, the low density of the polymeric media also results in low impact and the drifting phenomenon. Therefore, the effectiveness for dispersion is low. Furthermore, the low
