초록
Urushiol, mainly extracted from lacquer tree, is known to have excellent thermalstability, antibacterial properties, and antioxidant properties. Since urushiol cannot be effectivelysynthesized, it is common to extract it from lacquer tree using organic solvents. In this study,polyurushiol was successfully synthesized by simultaneous gamma-irradiation cross-linkingusing binary monomer mixtures (urushiol/3-(trimethoxysilyl)propyl methacrylate (TMPMA)and urushiol/dipentaerythritol hexaacrylate (DPEHA)) in various ethanol/H2O2 solutions. Thestructural changes and thermal properties of the synthesized polyurushiol were confirmedthrough Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM),thermal gravimetric analyzer (TGA), and contact angle measurements. Gamma-ray irradiationwas performed to grafting the monomer into urushiol with hydrophobic TMPMA or hydrophilicDPEHA, and it was confirmed that thermal behavior and moisture barrier properties wereeffectively improved through this.
