Structural-morphological characteristics and properties of fluorine-containing surface-modified poly(ethylene terephthalate) films

摘要

The surface modification of poly(ethylene terephthalate) films with polyfluorinated alcohols was studied. X-ray diffraction analysis, differential scanning calorimetry, and IR Fourier spectroscopy were used to determine that a modifier has a combined effect on the supramolecular structure of the polyester. The features of distribution of the modifier over the film surface are shown. The stabilizing effect of adding the modifier is discussed.
