摘要：

For the purpose of recycling waste polycarbonate (PC) products, PC hollow microspheres were prepared using waste PC products via a microencapsulation method. In the microencapsulation process, dichloromethane was the suitable organic solvent of the oil phase, and the optimal adding amount of gelatin was 1.7 g in 70 g water. The size of the PC hollow microspheres was analyzed by scanning electron microscopy (SEM). The hollow microspheres with mean diameter from 19 to 645 mu m could be obtained by varying the preparation factors. The tap density could be controlled through the manipulation of the weight ratio of W-1 and O phase and PC concentration.
