title: The Influence of Dimensional Effects on the Composition and Properties of Polydicarbonfluoride.
abstract: The influence of dimensional effects on the compositions and properties of polydicarbonfluoride (C2 F)n prepared from multilayered graphenes was investigated. Multilayered graphenes were produced by destructive thermal decomposition of intercalation compounds of "idealized" (C2 F)n that were obtained by reaction of gaseous ClF3 with natural graphite at a room temperature. The precursors of multilayered graphenes have a common formula (C2 F⋅xR)n where R is an organic or inorganic component. It was shown that polydicarbonfluoride prepared from multilayered graphene does not form stable intercalation compound with ClF3 , in contrast to polydicarbonfluoride prepared from graphite, that forms its intercalation compound with ClF3 during fluorination of initial graphite in the ClF3 excess. Investigations of polydicarbonfluoride prepared from multilayered graphene showed that it cannot form intercalation compounds with different classes of organic and inorganic compounds as polydicarbonfluoride prepared from graphite can do. The absence of such intercalation activity for polydicarbonfluoride prepared from multilayered graphene can be explained by high exfoliation degree of multilayered graphene (3-4 nm) along the c-axis that results in the presence of two-dimensional (2D) structure properties in multilayered graphene. Dimensional effects transformed the chemical properties of polydicarbonfluoride prepared from multilayered graphene and lowered its decomposition temperature by 150 K in comparison with polydicarbonfluoride prepared from graphite.
