摘要：Poly(ethylene terephthalate)/grafted carbon black (PET/GCB) and poly(ethylene terephthalate)/carbon black (PET/CB) composites were prepared by melt blending. The nucleating effect of CB and GCB were investigated using differential scanning calorimetry (DSC) analysis. The morphologies of the spherulites in PET, PET/CB and PET/GCB composites were observed by means of scanning electron microscopy (SEM). All results showed that GCB had higher nucleating activity than CB in PET and PET/GCB composite had higher rate of nucleation and crystallization. The melting behaviors of neat PET, PET/CB and PET/GCB composites after non-isothermal crystallization were investigated as well. It was evident that the melting behavior of PET is greatly influenced by addition of CB and GCB.
