Fluorinated Graphite Synthesis Of New Research

Graphite fluoride, which has been widely applied in the advanced country, is one of the most internationally attractive subjects in the contemporary research into new carbon /graphite materials of high technology, superior quality and remarkable profit. With excellent properties and distinct qualities, it is one of the most remarkable flowers in the new functional material families. As the most traditional and commonest method by which graphite fluoride is synthesized, "the vapor phase method" must use the extremely active and highly toxic fluorine gas as a source of fluorine, and the key technology details are rarely revealed in foreign documents, so synthesizing graphite fluoride is very difficult as well as dangerous, so far, there has not been published thesis of practice research on this subject nationwide and manufactured graphite fluoride in any domestic plant. As a result, perfecting the key technical of the vapor phase method which is namely the production of the fluorine gas, searching a new, safe, low cost solid sources of fluorine to eliminate the sheltering dangers brought about by fluorine gas, hunting and even preparing a new sources of carbon to ensure the superior qualities of graphite fluoride, and improving the synthesis technology of graphite fluoride to security, become the aim of the study and the main content of the thesis.Several aspects are mainly involved in this paper as follows through more than two years' hard work:The synthetic reactor for preparing the graphite fluoride was successfully designed and produced. The systematic research covered the technique of synthesizing the material by "the vapor phase method" and process. The small-sized experiment has been done in a factory.Graphite fluoride was successful synthesized by using an organic compound as the source of fluoride and the scale graphite as the source of carbon, i.e., the solid phase method. And the techniques of synthesizing have been researched one by one. Samples prepared by of the different techniques has been tested and analyzed synthetically.The successful synthesis of the graphite fluoride was in "the solid method" by using an inorganic compound as the source of fluoride and the scale graphite as theIIsources of carbon. And the techniques of synthesizing had been researched systematically. Its intrinsic nature has also been analyzed briefly. As a result, it cut a new way for the synthesis of the graphite fluoride.The various kinds of graphite fluoride and carbon fluoride synthesized with different sources of carbon have been studied. The best technological conditions have been analyzed and summarized. At the same time, the causes leading to the different quantities of the samples have been discussed.
