摘要

扫描探针显微镜（SPM

Scanning Probe Microscopy）是进行纳米材料表面性质测量的有力工具。制样是进行SPM观测的关键性技术。分子间作用力较强的纳米颗粒在制样过程中常常会发生二次聚合形成团簇

给SPM观测带来困难。针对纳米颗粒制样过程中的再聚合问题

本文提出了一种软印刷转印结合扩散的方法。利用基底表面的液膜对转引形成的纳米颗粒分布进行增强的扩散

从而得到适合SPM观测的纳米颗粒样品。验证实验结果表明此方法是一种可用于SPM观测纳米颗粒的有效制样手段。

Abstract

Scanning Probe Microscopy(SPM)is a powerful tool for detecting surface properties of nanomaterials.Preparing sample is the key process for SPM imaging.Detecting nanoparticles with SPM often faces the problem that the nanoparticles are usually repolymerized by the molecular force and form nanoparticle-reunions in the process of preparing SPM specimens.To conquer this difficulty

we propose a new method for preparing SPM nanoparticle specimens by soft microprinting combined with enhanced diffusing

in which proper nanoparticle dispersal system can be formed on the substrate surface separated in the liquor nano-film after soft-lithographed.Experiments vali-dated that it is an available artifice for preparing nanoparticle sample in SPM detecting.
