摘要

Corrosion remains a significant challenge across various industrial sectors, necessitating the development of advanced materials capable of providing enhanced protection in aggressive corrosive environments. Benzoxazine resins, known for their exceptional thermal stability, mechanical strength, and flame resistance, offer a promising solution. This study introduces a novel synthesis method for benzoxazine monomers utilizing tannic acid, aniline, and paraformaldehyde. Three monomers, designated as TA-BZ 1, TA-BZ 2, and TA-BZ 4, were successfully synthesized, with their names based on the molar ratios of phenol, paraformaldehyde (PFA), and amine. After curing the monomers at 180 °C, they were renamed TA-BZ A1, TA-BZ A2, and TA-BZ A4, respectively. The synthesized polybenzoxazines were comprehensively characterized. The primary objective of this research is to develop materials with superior mechanical and thermal properties, along with enhanced corrosion resistance. Extensive testing demonstrated that the cured materials exhibited not only outstanding mechanical and thermal stability but also favorable stress-strain behavior. Notably, the cured polybenzoxazine samples displayed significantly improved anticorrosion performance compared to their uncured counterparts. Among the monomers synthesized, TA-BZ A4 showed the most favorable results, with the highest corrosion potential, the lowest corrosion current density, and the lowest corrosion rate. The cured TA-BZ A4 demonstrated the best performance, with improved corrosion resistance due to enhanced cross-linking and adhesion. These materials show significant potential as protective coatings for industrial applications where corrosion resistance is essential.
