Abstract

In order to lessen the environmental pollution caused by coal gangue and facilitate its utilization in the polymer industry, a study on the melting and crystallization behaviors of coal gangue/Polybutylene adipate terephthalate (PBAT) composites was conducted using a differential scanning calorimetry (DSC). The results indicate that a small amount of coal gangue enhances nucleation ability, perfection degree of PBAT crystals, and accelerates PBAT crystallization rate. However, excessive coal gangue hinders PBAT crystallization. These outcomes are confirmed by Crystallization Rate Coefficient (CRC) and Mandelkern method.
