▎ 摘　　要

The ability to self-organize particles under the influence of an external excitation (magnetic field, electric field, temperature, light or crossed effect) is one of the most fundamental aspects of science, which can be directly transferred to practical applications. Magneto-or electro-rheological fluids are an example of using such phe-nomena. The most important challenge is to reduce the energy required to induce self-assembly in larger structures from fractured parts. In this paper the self-construction ability of graphene microparticles is presented. The main observation regarding the self-assembly of graphene foam in a thin glass capillary into a single chain in methanol upon applied DC electric field is reported. The mechanism of self-ordering of molecules is discussed in terms of charge separation in semi-conducting graphene particles upon an applied DC electric field. Additionally, in order to prepare thin coatings with fixed self-assembled graphene structures inside, silica hydrolysate was applied.
