METHOD FOR THE COLLECTIVE MANUFACTURE OF CARBON NANOFIBERS ON THE SURFACE OF MICROMOTIVE SURFACE MOUNTED ON THE SURFACE OF A SUBSTRATE AND STRUCTURE COMPRISING NANOFIBRES ON THE SURFACE OF MICROMOTIVES

摘要

The invention relates to a nanofiber fabrication method comprising nanofiber growth from a catalyst zone, furthermore comprising the following steps: producing at least one micropattern (11) on the surface of a substrate (1); producing a catalyst zone (50) on the surface of said micropattern; nanofiber growth from the catalyst zone, characterized in that the micropattern (11) comprises a base, at least partially convergent side walls and an upper face, said base being covered with a so-called poison layer (4) where no nanofiber growth catalysis effect can take place, the so-called poison layer not being present on said upper face; the base being covered with a catalyst layer (5) on the surface of the so-called poison layer; the thickness of the poison layer and the thickness of the catalyst layer being such that the nanofibers cannot grow either on the side walls or on the base of the micropatterns constructed beforehand.
