Investigation of Supermolecular Structure of Fluorine-Containing Polyethyleneterephthalate Monofibers

Аннотация

The effect of a new modifier based on a polyfluorinated alcohol immobilized on montmorillonite nanoclay on the supermolecular structure of polyethyleneterephthalate was studied by Fourier IR spectroscopy, x-ray structural analysis, DSC, DMA, and atomic-force microscopy (AFM). It was established that the effect of the fluorine-containing modifier, involving reorganization of the molecular and crystal structure of the polymer, is complex in nature, leading to an increase of the degree of crystallinity and raising the level of surface uniformity in the obtained polyester nanofibers.
