摘要

Nano-titanium dioxide (TiO2) was surface modified by isopropyl tri(dioctyl phosphate) titanate (NDZ-102 titanate coupling agent) using ultrasonic wet method, and pristine nano-TiO2 (P-TiO2)/poly(buthylene terephthalate) (PBT) and modified nano-TiO2 (M-TiO2)/PBT composites were prepared by melt-blending process in this paper. The modified Avrami and Kissinger models were applied to investigate the non-isothermal melt crystallization process of the PBT and TiO2/PBT composites by DSC measurements. The modified Avrami analysis showed the additions of TiO2 nanoparticles changed the crystallization behaviors of PBT, and accelerated the crystallization rate, and M-TiO2 could more increase PBT crystallization. Kissinger analysis showed the crystallization activation energy of TiO2/PBT composites were lower than that for pure PBT, and that of M-TiO2/PBT was smaller compared to the P-TiO2 /PBT composite.
