Triazine cored Schiff base multifunctional polybenzoxazine/bio-silica hybrid composites for enhanced flame and corrosion resistance
In this study, GPTMS-functionalized bio-silica reinforced Schiff base polybenzoxazine hybrid composites, based on a triazine-cored benzoxazine structure, were developed for high-performance thermal, flame retardant, and corrosion-resistant applications. Benzoxazine monomers were synthesized via Mannich condensation using triazine-based trisphenol (CN-IM) and four amines: aniline (a), furfuryl amine (fa), lauryl amine (la), and stearylamine (sa), with structural confirmation by FT-IR and NMR analyses. Among these, CN-IM-sa was selectively used for hybrid composite development due to its comparatively lower thermal stability, along with its inherent good corrosion resistance and superior hydrophobicity, aiming to enhance its protective performance through bio-silica reinforcement. Catalyst-assisted curing of CN-IM-sa reduced the curing temperature to 188 °C. The poly(CN-IM-sa)/bio-silica hybrid composite exhibited significant improvements, including a water contact angle of 130°, corrosion inhibition efficiency of 99.3 %, and improved thermal stability confirmed by high residual char. These results highlight the potential of CN-IM-sa/bio-silica hybrids as multifunctional coatings for corrosion protection in aggressive environments.
期刊介绍:
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
