Chimik oksidasyon se yon metòd komen ak enpòtan pou prepare grafit dilatabl. Oksidasyon se etap enpòtan nan prepare grafit dilatab pa oksidasyon chimik. Si reyaksyon entèrèksyon la ka kontinye san pwoblèm depann de degre ouvèti ant kouch grafit. Oksidan an fè atòm yo kabòn nan kouch adjasan nan kwen an grafit repouse youn ak lòt, ogmante espas ki la kouch, diminye enèji a aktivasyon nan reyaksyon a entèkalasyon, ak kreye kondisyon ki nesesè pou ajan an entèrèksyon insert nan kouch nan grafit san pwoblèm.

Chemical oxidation is a common and important method for preparing expandable graphite. Oxidation is the key step of preparing expandable graphite by chemical oxidation. Whether the intercalation reaction can proceed smoothly depends on the degree of opening between graphite layers. The oxidant makes the carbon atoms in adjacent layers of the graphite edge repel each other, increases the layer space, reduces the activation energy of the intercalation reaction, and creates necessary conditions for the intercalation agent to insert into the graphite layer smoothly.
