英文摘要Fuel system biodeterioration has persisted as an unresolved engineering challenge. The development of amphiphilic antibacterial agents holds immense significance for the inhibition of microbial activity and biofilm formation in oil-water interface in aircraft fuel tanks. In this study, we developed a hydroxypropyl trimethyl ammonium-O-alkyl chitosan (TTAC), an amphiphilic polymer with hydrophilic quaternary ammonium and hydrophobic alkyl chains, as a novel targeted (fuel-water interface-active) antimicrobial agent for aviation fuel system protection. Characterization was done using FT-IR and 1H NMR spectroscopy. The water contact angle measurement yielded a result of theta = 75.84 degrees. Antimicrobial performance showed potent activity with MICs of 8 mg/L (Acinetobacter lwoffii), 32 mg/L (Pseudomonas aeruginosa, Acinetobacter soli), 128 mg/L (Shewanella algae) and 64 mg/L (Escherichia coli, Staphylococcus aureus); MBCs were 16, 64, 256, and 128 mg/L respectively. Scanning electron microscopy (SEM) analysis of the fuel-water interface showed the densest biofilm at the interface, which was significantly reduced by TTAC treatment. TTAC treatment enhanced engineering stress by 11.9 % (Acinetobacter lwoffii) and 6.4 % (Pseudomonas aeruginosa) compared to untreated samples after microbial exposure. These results position TTAC as a promising multifunctional additive for next-generation fuel system preservation, offering simultaneous microbial control and metallic substrate protection. The amphiphilic action mechanism indicates specific utility in the complex fuel-water interface environments typical of modern aircraft fuel systems.
