采用反胶束法制备了C10 NH 2、C12 NH 2、C16 NH 2和C18 NH 2修饰的金纳米粒子。利用紫外-可见吸收光谱和LB技术研究了纳米粒子的稳定性及其二维有序排列。讨论了颗粒链长、粒径分布等因素对二维有序排列形成的影响。实验结果表明，包覆金纳米粒子的表面活性剂的链长越长，纳米粒子越稳定，纳米粒子的二维排列越有序。
Gold nanoparticles modified with C10NH2, C12NH2, C16NH2 and C18NH2 respectively have been prepared by the reverse micelle method. Nanoparticles stability and their two-dimensional (2D) ordered arrangement were studied by UV-Vis absorption spectra and LB technique. The factors, such as the chain length and the size distribution of particles, which affect the 2D ordered arrangement formation, are discussed. Experimental results show that the longer the chain length of surfactants capping the gold nanoparticles, the more stable the nanoparticles, and the more ordered 2D arrangement of gold nanoparticles.
