chloride (MDABP). Silver nanoparticles have been prepared through reduction method using trisodium citrate as reducing agent. The effect of the synthesized surfactant on the morphology and size distribution of the obtained silver nanoparticles has been followed by transmission electron microscope (TEM) and dynamic light scattering (DLS). The prepared surfactant MDABP with longer hydrophobic carbon chain
FTIR和1证实了四种合成的阳离子表面活性剂的化学结构1 H NMR光谱。表面活性剂是N-苄基-2-(癸酰氧基)-N-(2-羟乙基)-N-甲基乙氯化铵(MDABC),N-苄基-2-(十二烷酰氧基)-N-(2-羟乙基)-N-甲基乙铵氯化物(MDABL),N-苄基-2-(十四烷酰氧基)-N-(2-羟乙基)-N-甲基乙基氯化铵(MDABM)和N-苄基-2-(十六烷酰氧基)-N-(2-羟乙基)-N -甲基乙基氯化铵(MDABP)。已经使用柠檬酸三钠作为还原剂通过还原方法制备了银纳米颗粒。透射电子显微镜(TEM)和动态光散射(DLS)跟踪了合成的表面活性剂对所获得的银纳米颗粒的形态和尺寸分布的影响。所制备的具有更长的疏水性碳链的表面活性剂MDABP导致较小的粒度和窄的分布。表面活性剂对溶液行为的影响已使用20、40和60°C下的表面张力测量进行了评估。发现临界胶束浓度随着烃链长度和溶液温度的增加而降
