摘要/Abstract

摘要： 采用LB技术组装了一种三维有序的由十八胺修饰的纳米金颗粒多层结构.这是一种新的组装纳米颗粒三维有序聚集体的方法.为了扩大这种方法的适用范围,在组装过程中,将有机小分子1-苯基-5-巯基四氮唑引进结构,形成了新的纳米金颗粒多层聚集体.这两种多层膜经透射电子显微镜和小角X射线衍射测量证明构成多层膜的单层膜上的纳米金颗粒是有序的,并且颗粒在层与层之间的排列也是有序的.

Abstract: Octadecylamine coated-nanogolds formed a three-dimensional ordered structure by LB technique.This was a new method to construct three-dimensional ordered aggregates.In order to enlarge the usage of the method,during the construction,organic small molecule,1-phenys-5-mecaptotetrazole was assembled into the interlayers,a new multilayer was formed.The two multilayers had ordered particles both on planes and in layer by layer,which were confirmed by TEM images and small-angle X-ray diffraction measurement.

Key words: Langmuir-Blodgett technique, assemble, ordered nanogolds
