HFA(Hexadecafluorodecane-1,10-diyl bis(3-phenylacrylate)) synthesized using fluorine compounds to give hydrophobic surface properties of UV reactive self-healing polymers has a cinnamate function at terminal group, so [2+2] cycloaddition is designed to self-healing through reaction. WCA(water contact angle) was used to analyze the hydrophobic properties of this monomer, and in the HFA has a hydrophobic surface at about 105°. In addition, UV-spectroscopy is ussed to analyze the reaction rate of [2+2] cycloaddition, and it can be seen that the UV absorption rate of the cinnamate functional group is also increased due to the high electronegativity of fluorine. In order to identify the properties of self-healing, observation using optical microscopy and confocal microscopy showed that self-healing was possible. The monomer designed by this study is a water repellency self-healing polymer with fast curing speed and is expected to be application to various coating material.
