    摘要: A stable blister free flexible graphite is formed in accordance with the present invention by performing two chemical reactions including a first step of high temperature heat treatment which converts the active carbon surface from hydrophilic to hydrophobic and generates active surface sites and a second step of exposing the heat treated graphite to a stabilizing reagent for stabilizing the active sites generated by the first step of high temperature heat treatment.

    摘要: A process for forming pinhole free ultra-thin flexible sheet material from natural graphite comprising treating low ash natural graphite particles with an oxidizing agent to intercalate the graphite, introducing the particles after they are dried to less than 2% by weight water into a furnace preheated to at least 2000.degree. F. to cause rapid expansion to a specific volume of at least 800 cc/gm and compressing the expanded graphite to below 8 mils in thickness with a density of less than 1.3 g/cc.
