新型含刚性环己烷结构的氟代丙烯酸酯的制备及其性能研究.

Fluorine-containing liquid crystal polymers have excellent hydrophobic stability, so they have attracted much attention in the field of stable hydrophobic coatings. Thus, a novel fluoroacrylate (FAM) containing rigid cyclohexane structure was simply synthesized to improve the hydrophobic stability of fluoropolymers using isophorone diisocyanate (IPDI), hydroxyethyl methacrylate (HEMA) and perfluorohexylethanol (S104) as raw materials. The structure, liquid crystal behavior, thermal properties, and hydrophobic properties of monomers and homopolymers were studied by Fourier transform infrared spectrometer, nuclear magnetic resonance spectrometer, X-ray diffractometer, polarizing microscope, differential scanning calorimeter, thermogravimetric analyzer, and static/dynamic water contact angle measuring instrument and dodecafluoroheptyl methacrylate (DFMA) used as a reference substance. The results showed that the synthesized product was a fluoroacrylate containing a rigid cyclohexane structure. The monomer and homopolymer are thermotropic liquid crystals, which facilitate the dense distribution of fluorocarbon chains at the end of the homopolymer side groups and prevent surface group reconfiguration when the homopolymer comes into contact with polar liquids, resulting in better thermal stability, hydrophobicity and hydrophobic stability.
