Effects of Nanoparticles TiN on the Crystallization Behavior of PET Nanocomposites
In this paper, crystallization kinetics behavior of a high heat-absorbing PET / TiN nanocomposite ,the effect of the crystallization behavior of adding nanoendothermic agent,and their crystallization rate and crystallization were studied by differential scanning calorimeter (DSC) ,researching the effect of crystallization behavior of PET with modified TiN and using Avrami equation to study non-isothermal crystallization kinetics. The results show that the kinetic rate constant Zc increasing with the increase of cooling rate, the crystallization half time t1 / 2 subsequently reduced, the crystal growth become fast; TiN is a good nucleating agent in PET, improve PET’s crystallization rate, adding TiN reduce the crystallization activation energy. This has important significance to guide nanocomposite processing.
