Abstract

A comparative analysis has been performed for the structure of ring deposits resulting from the evaporation of droplets of aqueous dispersions of gold nanorods and composite nanoparticles with a gold core/organosilica shell structure based thereon. The nature of the particles has been shown to have a key effect on the character of their packing near a three-phase contact line. The study of the conductivity of the ring deposits obtained from dispersions of the composite particles has shown that it is realized via over-barrier electron emission.

各向异性纳米颗粒性质对分散液滴蒸发引起的环状沉积物性能的影响

摘要

已经对由金纳米棒和具有基于其的金核/有机硅壳结构的复合纳米颗粒的水分散体的液滴的蒸发产生的环沉积物的结构进行了比较分析。已经表明，颗粒的性质对其在三相接触线附近的堆积特性具有关键影响。对由复合颗粒的分散体获得的环状沉积物的电导率的研究表明，它是通过过势垒电子发射实现的。
