Abstract
(EN)
This invention provides a nanodisk, which can be formed of a wide variety of materials and has a high level of application, and a method for manufacturing the same. The nanodisk comprises fundamental units formed of two-molecule block copolymers arranged in series in a main chain direction, the fundamental units having been aggregated in a plane direction. The nanodisk has a thickness of 1 nm to 100 nm, a diameter of 10 nm to 5 μm, and an aspect ratio of not less than 1. Since the thickness of the nanodisk is not more than 100 nm, the nanodisk is transparent to light in a visible region. Further, when a metal element is held on the crosslinked structure part, the nanodisk can be utilized as a nanodisk having magnetic properties and electroconductive properties, or a nanodisk having catalytic activity and a high refractive index. Thus, the nanodisk can be applied to a wide variety of fields such as fine particle/powder technology, colloid surface science, electronic materials, and optical materials.

La présente invention concerne un nanodisque, pouvant être formé d'un large éventail de matériaux et ayant un niveau élevé d'application, ainsi qu'un procédé de fabrication de ce nanodisque. Le nanodisque comprend des unités fondamentales formées de copolymères séquencés à deux molécules disposés en série dans la direction de la chaîne principale, les unités fondamentales ayant été agrégées dans une direction planaire. Le nanodisque a une épaisseur comprise entre 1 nm et 100 nm, un diamètre compris entre 10 nm et 5 µm, et un rapport longueur/diamètre supérieur ou égal à 1. L'épaisseur du nanodique étant inférieure ou égale à 100 nm, le nanodisque est transparent à la lumière dans une région visible. En outre, lorsqu'un élément métallique est maintenu sur la partie de structure réticulée, le nanodisque peut être utilisée en tant que nanodisque ayant des propriétés magnétiques et des propriétés électroconductrices, ou en tant que nanodisque ayant une activité catalytique et un indice de réfraction élevé. Le nanodisque peut donc être utilisé dans un large éventail de domaines, tels que la technologie des fines particules/poudres, la science des surfaces colloïdes, les matériaux électroniques et les matériaux optiques.
