The paper considers the possibility of achieving superconductivity in nanosized graphite particles due to the capillary pressure effect. Graphite has unique electronic properties due to its specific crystalline structure, but the low density of charge carriers limits its use as a superconductor. Hypothetically, the increase in pressure inside a graphite nanoparticle caused by surface tension can lead to a significant increase in the electron density and, as a consequence, to the occurrence of superconductivity at higher temperatures. This paper theoretically substantiates this hypothesis and estimate possible values of the critical temperature of the transition to the superconducting state.
