摘要:
对于用十二烷基硫醇包覆的金纳米微粒,用Langmuir-Blodgett(LB)技术制备了二维金纳米微粒有序阵列.在单纯的硫醇包覆的金纳米微粒形成的LB膜中,由于硫醇分子之间的疏水相互作用,容易导致金纳米微粒的自组织而在LB膜中形成缺陷.为了改善金纳米微粒的成膜性能和提高金纳米微粒阵列的有序性,正十二醇作为添加剂和润滑剂加入到金纳米微粒的氯仿溶液中与金纳米微粒一起形成LB膜.用透射电子显微镜对金纳米微粒的二维阵列进行了表征.结果表明,正十二醇的加入可以有效地减少用LB技术制备的二维金纳米微粒阵列中的缺陷,提高金纳米微粒阵列的有序性.
Abstract:
Herein, Langmuir-Blodgett(LB)technique was used to fabricate two-dimensional arrays of gold nanoparticles, which were encapsulated with 1-dodecanethiol molecules. In the LB films of unique encapsulated gold nanoparticles, defects are incident to form due to the self-organization of gold nanoparticles originating from the van der waals interaction between ligands. In order to improve the quality of the nanoparticle films, 1-dodecanol was added into the samples and served as lubricant to make the film more ordered. The two-dimensional gold nanoparticle arrays were characterized with transmission electron microscope(TEM), which indicated that the addition of 1-dodecanol could efficiently shoot defects in the LB films of encapsulated gold nanoparticles and enhance the order of the nanoparticle arrays.
