Four cationic surfactants of quaternary hexammonium silane chloride based on hexamethylenetetramine and alkyl chloride were synthesized. The chemical structures of the prepared cationic surfactants were elucidated using Fourier transform infrared (FT‐IR) spectroscopy and mass spectrometry analysis. The surface and thermodynamic properties of the prepared surfactants were also studied. The performance of these cationic surfactants as microfouling agents against two strains of Gram‐negative bacteria, namely, Pseudomonas aeruginosa and Escherichia coli , and two strains of Gram‐positive bacteria, namely, Staphylococcus aureus and Bacillus subtilis , were evaluated as antimicrobial agents. The results showed that the maximum antimicrobial activity was detected for N ‐hexamethylenetetramine‐ N ‐ethyl silane ammonium trichloride (Ah). The maximum and minimum antimicrobial activities were 73 and 60 % against S. aureus and E. coli , respectively, at a concentration of 5 mg/l, pH 7, and 37 °C.
