摘      要：The chemical structure of newly synthesized cationic surfactants based on Schiff base was confirmed using Fourier transform infrared spectroscopy,proton nuclear magnetic resonance spectroscopy,and mass *** synthesized surfactants were used in the synthesis of silver nanoparticles by a simple one-step *** silver nanoparticle（AgNPs） formation was confirmed using transmission electron microscopy（TEM）,electron diffraction（SAED）,dynamic light scattering（DLS）,and energy dispersive X-ray spectroscopy（EDX）.The structure of the surfactant played an important role in the synthesis *** the hydrophobic chain length,the stability,and the amount of surfactant increased the quantity of AgNPs *** surface activity of the synthesized cationic surfactants was determined using surface tension measurements at three different *** synthesized surfactants showed a high tendency toward adsorption and *** the hydrophobic chain length of the synthesized surfactant increased its *** the synthesized cationic surfactants and their nano-form against bacteria and fungi showed that they are highly *** silver nanoparticles enhanced the biological activity of the synthesized cationic surfactants.
