Ionic Liquids - Novel Tenside like Materials for size controlled Preparation of Nanoparticles and safe-to-handle Nanoparticle Dispersions

摘要

Ultra small Ag and Ru nanoparticles with a narrow size distribution have been synthesized in ionic liquids using reductive, thermal or photochemical conditions. The influence of the ionic liquid on the size of the nanoparticles has been investigated. In addition stable dispersions of different kinds of MWCNT in water have been prepared by the addition of ionic liquids as novel tenside like materials to a mixture of the MWCNT in water. These dispersions have been characterized by Photon Cross Correlation Spectroscopy (PCCS).
