Beschreibung
Zusammenfassung:	The invention provides a novel conductive film and a multilayered conductive structure, comprising a plurality of metal nanowires arranged in clusters and having an average aspect ratio of least 100,000, optionally decorated by metal nanoparticles. It is also disclosed a process for preparation of a conductive film comprising metal nanowires by surfactant/template assisted method which involves the use of a precursor solution based on surfactant (such as CTAB), metal precursor (such as HAuC14 and AgN03) and reducing agent (such as metal borohydride or sodium ascorbate). La présente invention concerne un film conducteur et une structure conductrice multicouche innovants, comprenant une pluralité de nanofils métalliques agencés en faisceaux et ayant un rapport d'aspect moyen d'au moins 100 000, éventuellement décorée par des nanoparticules métalliques. L'invention concerne également un procédé de préparation d'un film conducteur comprenant des nanofils métalliques au moyen d'un procédé assisté par tensioactif/modèle qui implique l'utilisation d'une solution précurseur à base d'un agent tensioactif (tel que CTAB), d'un précurseur de métal (tel que HAuC14 et AgNO3) et d'un agent réducteur (tel qu'un borohydrure métallique ou l'ascorbate de sodium).
