Fluorination of lyophilized graphene oxide and graphene oxide-C60. Fluorination of graphite, graphite oxide and subsequent reaction of the prepared products.

Original language description

Oxidization of graphene and joint oxidization of graphene and fullerene C60 in various weight ratios were used to produce water suspensions that allow preparation of foils with various morphologies which can be further treated, e.g. by fluorination, bromination, embedding of catalytic-active metals, preparation of composite materials with other polymers or nanofibers and also as lamellar fibers prepared by freeze drying without any additional components. In this work we have focused on fluorination of water suspensions of graphene oxide and graphene oxide–fullerene C60 after their lyophilization. The resulting products were characterized with microscopic imaging techniques, SEM, FT IR, EDAX elemental analysis, TGA and DSC analyses. The paper also revives author´s results which date back to 1985 when he dealt with fluorination of graphite and graphite oxide with elemental fluorine and subsequent processing of fluorination products. The obtained products, then called by the author hydrogen graphites, fluoride graphite and chloride graphite, are now known under as graphane, fluorographene and chlorographene respectively. This work deals with preparation of materials with amphiphobic properties, based on graphene oxide – fluorine and graphene oxide – C60 – fluorine.
