Abstract: Disclosed is a process of manufacturing a chemically reduced graphene oxide/silicon nanowire composite. The formation of the three-dimensional monolith and the chemical reduction of graphene oxide by a reducing agent selected from hydrazine hydrate, ethylene diamine and 1,4-diaminebutane are in one step. Also disclosed is a chemically reduced graphene oxide/silicon nanowire composite that can be obtained by the disclosed process. The composite is a three-dimensional monolith in which the two components are covalently linked each other, having a high degree of reduction with a C/O ratio of 1-50, preferably from 10 to 25, more preferably 16.7, having a porous structure and a high specific surface area of 50-5,000 m2/g, preferably 800-2,500 m2/g, more preferably 1,433 m2/g and having a low resistance to charge transfer from 0.1 to 5 ?, preferably from 0.3 to 1.5 ?. Also disclosed is a lithium-ion battery or a supercapacitor including the composite (or monolith).

Abstract: The invention concerns a method for grafting molecules of interest on a silicon substrate via a spacer compound, said grafting including at least one click chemistry reaction to the supports thus obtained as well as their uses in nanotechnologies and nanobiotechnologies, such as molecular electronics, the manufacture of biochips or of sensors.
