【摘要】：針對(duì)傳統(tǒng)方法制得的膨脹石墨含硫量高和膨脹容積不穩(wěn)定的問(wèn)題,以0.28mm的鱗片石墨為原料,KMnO_4為氧化劑,HClO_4和H_3PO_4為插層劑,經(jīng)微波爐和馬弗爐兩種膨脹方式對(duì)可膨脹石墨的膨脹容積進(jìn)行測(cè)試,采用正交實(shí)驗(yàn)法確定了最佳工藝條件。結(jié)果表明:在石墨(g)∶混酸(mL)∶高錳酸鉀(g)=1∶4.5mL(3.6mL高氯酸∶0.9mL磷酸)∶0.3,反應(yīng)溫度30℃,反應(yīng)時(shí)間60min,抽濾洗滌至pH值為5~7,80℃干燥,于微波爐中高溫膨脹,膨脹容積最大,可達(dá)350mL/g。

The results showed that the optimum technological conditions were determined by orthogonal experiment . The results showed that the best technological conditions were determined by orthogonal experiment . The results showed that the best technological conditions were determined by orthogonal experiment . The results showed that the best technological conditions were determined by orthogonal experiment . The results showed that the best conditions were as follows : ( g ) : mixed acid ( mL ) : potassium permanganate ( g ) = 1 : 4.5 mL ( 3.6 mL of high chlorhydric acid : 0.9 mL phosphoric acid ) : 0.3 , reaction temperature 30 鈩，
