Effect of nano-fillers on the thermal performance of pCBT resin

Abstract

In this paper, the influence of nano-graphite and nano-TiO2 with the content of 0.5 wt.% to 2 wt.% on the thermal properties of polymerized cyclic butylene terephthalate (pCBT) resin was investigated by Differential scanning calorimetry (DSC) and Thermo gravimetric analysis (TGA), respectively. The experiment results show that the degree of crystallinity of the material decreases with the increasing of nano-particles content. Furthermore, it is found that two melting peaks appearing during the second heating in DSC curves. Meanwhile, with the increasing of nano-TiO2 content, the decomposition rate of the resin decreases slightly in TGA curves.
