Abstract.  The majority of currently available methods of graphene production have certain drawbacks limiting its scaling. Unlike the others, liquid-phase exfoliation of graphite is a promising technique for high-yield graphene production. In this work, we present our results on one- to four-layer graphene production using various solvents and surfactants from flaky graphite. We suppose that the initial graphite in the form of millimeter-size flakes can be more advantageous for extended graphene flake acquisition than graphite powder consisting of tiny particles used in previous works. Half-centimeter–size graphene films were obtained by depositing exfoliated flakes on an arbitrary substrate. Such films can be useful for electronic and photonic applications.
