Analysis of the influence of different proportions of polyethylene 2,5-furandicarboxylate(PEF)on the properties of polyethylene terephthalate(PET)
This paper improves polyethylene terephthalate(PET)blended with bio-based polyethylene 2,5-furandicarboxylate(PEF)in different proportions.The improvement effect of PEF on the mechanical properties,water vapor transmission rate,oxygen transmission rate and glass transition temperature(Tg)of PET is studied.Mechanical properties show that with the increase of PEF content,the mechanical properties of PET increase to a certain extent.Barrier property tests show that PEF has a significant improvement on the barrier property of PET.The test results of glass transition temperature show that the glass transition temperature of PEF is higher than that of PET,and the heat resistance is good.In addition,electron microscopy is used to analyze the blending compatibility effect of PEF and PET,indicating that the two materials have excellent compatibility.
