Title: ANTHRACENE-PERFLUOROPOLYETHER-BASED SUPERHYDROPHOBIC SURFACE TREATMENT AGENT AND METHOD FOR SUPERHYDROPHOBIC SURFACE TREATMENT OF PET FIBER USING SAME
Abstract:
The present invention relates to an anthracene-perfluoropolyether-based superhydrophobic surface treatment agent and a method for superhydrophobic surface treatment of a PET fiber using the same. More specifically, the present invention provides a method for superhydrophobic surface treatment of a PET fiber, the method comprising the steps of: feeding polyethylene terephthalate (hereinafter, "PET"), an anthracene-perfluoropolyether-based superhydrophobic surface treatment agent, and a fluorine-based solvent into a reactor (first step); heating the reactor to perform superhydrophobic surface treatment on a PET surface through a dyeing reaction of the superhydrophobic surface treatment agent (second step); and washing and drying the superhydrophobic surface-treated PET surface (third step). The treatment of the PET fiber surface with the bio-environmentally friendly anthracene-perfluoropolyether-based superhydrophobic surface treatment agent according to the present invention has advantages of excellent superhydrophobicity, regeneration in which initial superhydrophobicity is again restored, industrialization, and area enlargement, without damaging air permeability and physical characteristics of fabrics. Furthermore, the PET fiber treated with the superhydrophobic surface treatment agent can be applied to various industries, such as functional clothing, medical materials, and water and oil separators.
