摘要：

In order to explore the effects of zero-dimensional carbon nanomaterials-carbon dots (CDs) on the thermodynamic, flame-retardant, mechanical and fluorescent properties, a copolymer flame retardant with a good flame-retardant effect on poly(ethylene terephthalate) (PET) was selected. 2-carboxyethyl phenyl hypophosphorous acid (CEPPA) and carbon dots were added to the PET matrix by in-situ polymerization, and the effect of carbon dot addition on various properties of FRPET was studied. The effect of different carbon dots on the performance of FRPET was analyzed through limiting oxygen index (LOI), vertical combustion (UL94), cone calorimetry (CONE) and other tests. The results of the study show that the LOI value of FRPET reaches up to 34%, when the carbon dots addition is 1.50% and the vertical combustion is at the V-0 level. Compared to FRPET with only CEPPA addition, the ignition time is extended and the peak heat release rate reduced, the average heat release rate and the total heat release decreased. In addition, the mechanical properties of FRPET after the addition of CDs are also greatly improved and give FRPET fluorescent properties, which is beneficial for broadening the application fields of FRPET. © 2021, Periodical Agency of Journal of Textile Research.
