Research Progress of Nanomaterials Modified Polyethylene Terephthalate
The research status of polyethylene terephthalate(PET)modified by nano-materials in recent years is reviewed.The modification methods of PET composites were introduced.The effects of fillers on the improvement of mechanical properties,crystallization properties,thermal stability,heat transfer properties,and barrier properties of PET composites were summarized from two aspects of common nano-material modification and two-dimensional nano-material modification.It is pointed out that the homogeneous dispersion of nano-fillers in the matrix is beneficial to reduce the activation energy of crystallization and increase the free volume of PET segments,thus improving the crystallization properties of PET.The application of two-dimensional nano-materials in PET modification is prospected.
