摘要

A lasting high surface energy co-polyester poly[ethylene terephthalate-co-ethylene isophthalate sodiosulfonate-co-poly(ethylene glycol)] polyester (PEPST) was synthesized and applied in laminated tin-free steel (TFS). The structures and properties of the copolyester were characterized by nuclear magnetic spectra (1(H)-NMR), thermogravimetry, differential scanning calorimetry, polarized optical microscopy, and surface energy tests. Meanwhile, the peel strength and corrosion resistance of the co-polyester film were also measured. The results confirm that an improvement in the lamination temperature leads to PEPST film peel strength increases, and crystalline and corrosion resistance decrease. Based on the purpose of reducing a detrimental effect on corrosion resistance, a reasonable lamination temperature was determined. Scanning electron microscope and energy dispersive X-ray analysis prove the interface combination morphology of laminated TFS. Anticorrosion property analysis shows PEPST film has good anticorrosion performance. (C) 2017 Wiley Periodicals, Inc.
