Non-isothermal Crystallization Kinetics of Cu/MDPE Composites Prepared Using Ball Milling Method

The crystallization of pure MDPE and its Cu composites have been investigated under non-isothermal condition using differential scanning calorimetry (DSC).Different milling time and copper volume percent were applied. According to the results, the Avrami indexes showed the spherulite growth mechanism incrystallization of samples. Also, the apparent activation energies obtained from two methods (Kissinger and Ozawa) showed good agreement. Furthermore, bychanging the cooling rate and adding Cu particles, some noticeable results were obtained from dX/dt plots
