摘要
通过混酸法制备了两种不同氧化剂体系的可膨胀石墨(EG),并采用膨胀容积和X射线(XRD)对EG进行了表征。实验结果表明:K2Cr2O7为氧化剂制备的可膨胀石墨,氧化充分,插层效果好,膨胀容积(EC)大,K2Cr2O7同石墨的最佳比例是0.8∶10。
Two EG systems doped different oxidants were prepared by blended acid and characterized by expandable capacity and XRD. The results showed that the EG used K2Cr2O7 as oxidant has enough oxidation, effective insertion, big expandable capacity and the effect is the best when the ratio of K2Cr2O7 to graphite arrives at 0.8:1.
