Phase-Transfer Assisted Self-Assembly of Noble Metal Nanoparticles

摘要

A phase-transfer assisted experimental procedure has been developed for the self-assembly of noble metal nanoparticles prepared by wet-chemistry methods. The protocol calls for firstly the mixing of the metal hydrosol with an ethanol solution of alkylamine, and then the extraction of the alkylamine-stabilized metal nanoparticles into a non-polar organic solvent (such as toluene, hexane, or chloroform). This method offers an effective approach to assemble metal nanoparticles on a substrate. It is therefore an attractive alternative for the preparation of self-assembled nanoparticle layers.View full textDownload full textKeywordsPhase-transfer, Self-assembly, Metal, Nanoparticles, AlkyamineRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10584587.2012.686737
